As a true nucleus, mitochondria, and chloroplasts.In the origin of the eukaryotes, endosymbiosismost likely began with a heterotrophic endosymbiont entering the cell as undigested prey or as an internal parasite.Scientists believe that endosymbiosis most likely began with a heterotrophic endosymbiont entering a cell as undigested prey or as an internal parasite.During the origin of the eukaryotic cell, it is thought that engulfed bacteriadid not initially have a mutually beneficial relationship with their hosts, but later evolved one.The engulfed bacteria probably entered the host cell as undigested prey or internal parasites. Ultimately, they evolved to become the mitochondria and plastids of eukaryotic cells. So, they did not initially have a mutually beneficial relationship with their hosts but later evolved one.Which of the cells shown in the figure are eukaryotic cells? 6, and 7All eukaryotic cells have a nucleus, endomembrane system, and mitochondria. So, of the cells shown, 5, 6, and 7 are eukaryotic cells.The earliest organisms were most likely __________.ProkaryoticProkaryotes originated a few hundred million years after Earth's crust cooled and solidified.Which of the following lists most likely represents the correct sequence, from earliest to most recent, in the origin of cell organelles and cellular organization?photosynthetic prokaryotes, mitochondria, chloroplasts, multicellular eukaryotesThis evolution of cell organelles can be explained by endosymbiosis theory. When a large cell engulfed small cell, some of these small cells provided energy to them and became mitochondria, others made food and became chloroplast.Prokaryotic cells are found in the domain(s) _____.Bacteria and ArchaeaBoth of these domains are composed of prokaryotic cells.In the five-kingdom system, prokaryotes are placed in the kingdom _____.MoneraAll monerans are prokaryotes.A human is classified in domain _____ and kingdom _____.Eukarya ...

Are problems with your mitochondria. And I’ve written extensively about this, they actually are so easily and quickly digested into sugars and simple fats, that it causes rush hour in your mitochondria. And your mitochondria rather than boosting your energy literally failed to produce the energy you need. And all of a sudden following lunch, you found yourself not able to concentrate, not able to focus on your work, and literally wanting to put your head down for a few minutes to recover. If you find that pattern consistently happening, the first thing I want you to do is consider what you’re actually having for lunch. And consider that that need for the afternoon power nap is actually being driven because of literally how tired and sleepy you are. And it may be a power failure of your mitochondria that’s actually causing the problem. On the other hand, if we’ve already looked at that possibility, and that is not happening with you, there are actually good recommendations why many cultures use a nap midday or early in the afternoon. It can actually support your memory. Studies have shown that sleep promotes an important role in storing memories. A nap can actually help you remember things you learned earlier in the day, as well as a full night’s sleep. And interestingly enough, napping can actually keep you from forgetting things like motor skills, sense perception, and verbal recall too. Now you actually may be able to connect dots easier. It turns out that if you nap after learning something, you can actually store those memories easier than if you waited all day to do the same thing and go to sleep. In fact, the same thing happens at night. Many people find and studies show that if you want to learn something and have it stick, studying right before a nap, or right before you go to sleep, is one of the best ways to make it stick. Now, it might help you climb the corporate ladder. When you do a task over and over throughout the day. Most of us notice that their performance gets worse as the day goes on. And studies show that a 15-minute power nap can actually make you more consistent and kind of reset the clock. I can tell you during my career as a surgeon, that two or three times a week, we would.

The word BioPerine.And if you see that, that’s your key, that you’ve got the agent to absorb it. Why get curcumin in your body? Number one, it’s one of the few polyphenols that has been shown to cross the blood brain barrier. Most drugs, most compounds cannot get through this barrier called the blood-brain barrier. And turmeric is one of those rare ones, and that may explain why it has been associated with improved memory. Now, turmeric curcumin also is a strong mitochondrial uncoupler. That means it actually tells mitochondria to repair themselves and to make more mitochondria called mitogenesis. And it has the additional benefit in having mitochondria waste fuel. And there are a number of studies suggesting that curcumin actually helps maintain a healthy weight or helps with weight loss through thermogenesis. Speaking of thermogenesis, there are numerous studies that show changes white fat into beige fat. Now, there are three types of fat.There’s brown fat, beige fat, and white fat. The fat that we store fat in is basically white. It’s fat. Brown fat is name brown fat because it’s so loaded with mitochondria that it literally looks brown under the microscope. Brown fat is used to generate heat. In fact, when we’re babies, we have a lot of brown fat in our body and we use that brown fat to generate heat through mitochondrial uncoupling. Beige fat is white fat that’s becoming more and more and more filled with mitochondria. So guess what? Turmeric curcumin actually makes that transition happen. And the more beige fat you have, the more brown fat you have, the healthier you are. And you’ve seen in my last books like Longevity Paradox, Energy Paradox, Unlocking the Keto Code, how important activating brown fat in beige fat is in your long-term health

To the kidneys. Femorals deliver blood to the legs & the caudalartery takes blood to the tail.The posterior mesenteric delivers blood to manyorgans & tissues in the lower abdominal area.Source: Mitochondria are redistributed towards the cell membrane in the muscle fibers of Bar-headed Geese. (a) The proportion of mitochondria that were subsarcolemmal was higher in Bar-headed Geese than in low altitude species. Grey bar, Bar-headed Goose; unfilled bar, Barnacle Goose; black bar, Pink-footed Foose.

Arrow, subsarcolemmal mitochondria; arrowhead, intermyofibrillar mitochondrion.Adaptation for high-altitude flight -- Bar-headed Geese (Anser indicus) migrate over the Himalayas at up to 9000 m elevation, but it is unclear how they sustain the high metabolic rates needed for flight in the severe hypoxia at these altitudes. To better understand the basis for this physiological feat, Scott et al. (2009) compared the flight muscle of Bar-headed Geese to that of low altitude birds (Barnacle Geese, Pink-footed Geese, Greylag Geese, and Mallard ducks). Bar-headed Geese had more capillaries per muscle fiber than expected, and higher capillary densities and more homogeneous capillary spacing. Their mitochondria were also redistributed towards the sarcolemma (cell membrane) and adjacent to capillaries. These alterations should improve O2 diffusion capacity from the blood and reduce intracellular O2 diffusion distances, respectively. Bar-headed Geese have, therefore, evolved for exercise in hypoxia by enhancing the O2 supply to flight muscle. Bar-headed Geese BBC Worldwide - Bar-headed Geese Most birds

Tongue and throat problems may make it hard to eat. Surgery can help fix your ptosis. You might need occupational therapy or another surgery if other parts of your body are affected.13/15DiabetesOver time, high blood sugar can damage blood vessels and nerves in and around your eyes. You might get a droopy eyelid along with double vision. That can happen with diabetic third nerve palsy. Symptoms sometimes get better when you manage your diabetes. But the doctor might suggest surgery if your ptosis affects your vision and lasts longer than 6 months.14/15BotoxBotulinum toxin (Botox) can paralyze your muscles, like the ones that cause wrinkles. You might not have any problems with Botox. But it’s possible for the toxin to get into the muscle that controls your upper eyelid. Your ptosis should get better as it wears off, but apraclonidine eyedrops might help. Your doctor will help you decide what treatment is right for you.15/15Mitochondrial MyopathiesGenetic diseases can make it hard for mitochondria to work. That’s what powers most of the cells in your body. Your eyes and eyelids might get weak. It may cause mild vision problems in adults. Kids with mitochondria issues should get eye exams often. The doctor might give you nutrition supplements like creatine, carnitine, or coenzyme Q10 to help your mitochondria. More research is needed to know how well these supplements work.

MTOR (mammalian or mechanistic target of rapamycin regulates growth and development, which is great when you are young. But as you age, excess mTOR activity contributes to inflammation and its numerous problems. LE: Moving on to mitochondria…why do you call these little power stations "a necessary evil?" SK: A long, long time ago, mitochondria were their own energy-efficient little cells that became engulfed by bigger cells and, eventually, semi-autonomous organelles within those cells. They're a victim of history because they evolved when oxygen was very rare, and now it's not rare. So mitochondria find themselves extremely vulnerable to free radicals. Mitochondria use oxygen, but get destroyed by it. The more they work, the more they damage themselves. It's kind of sad. Mitochondria make their own endogenous antioxidants, but over time can't make enough. Fortunately, there are several things that can help them out: astaxanthin, curcumin, quercetin, resveratrol or pterostilbene, and nicotinamide. When too many mitochondria are damaged, energy production drops, which affects all of the other categories and is why old people tend to feel tired a lot. LE: Why is waste management so important? SK: When you combine excess glucose and oxidative stress, you get advanced glycation end products, known by the wonderful acronym AGEs. AGEs age you because glucose is sticky and gums up the works of everything it latches onto, including DNA and proteins, eventually causing structural failure and dysfunction. It's why our arteries stiffen and skin sags. But several agents can either strip away AGEs or inhibit their formation. Some of the best are carnosine, curcumin, pyridoxamine (a form of vitamin B6), rosmarinic acid and our old friend metformin. LE: You include 14 anti-aging "molecular agents" in your book. Do people have to take them all? SK: The more the merrier. Although they may overlap to. How did mitochondria come about?

The University of Florida's athletic teams, known as the Gators, have a storied history, filled with traditions, rivalries, and a unique fashion statement that's become an internet sensation: Florida Jorts. What started as a playful jab has evolved into a cultural identifier for fans of the Gators. But why do these particular jean shorts stir such passion and humor in the world of college sports? In this exploration, we'll delve into the origins of the jorts phenomenon, examine the discussions it has sparked, and investigate how the trend has been perpetuated through humor and stereotypes. Join us as we uncover the story behind the infamous Florida Jorts and their place in collegiate folklore.Index What are jorts and how did they originate? Do Florida Gator fans really wear jean shorts? The debate within the Florida Gator community How the term "jorts" spread across SEC schools Humor and stereotypes surrounding jorts Embracing or rejecting the jorts narrative Related Questions about Florida Jorts Are Jorts in Style in 2024? Where Did the Term Jorts Come From? What Is the Difference between Jorts and Jean Shorts? What Do Jorts Mean? What are jorts and how did they originate?Let's start by defining our subject. Jorts, a portmanteau of 'jean' and 'shorts', are exactly what they sound like: shorts made from denim fabric. Their history can be traced back to the 1960s and '70s when repurposing old jeans into shorts became a practical fashion trend. Over the years, jorts have cycled in and out of fashion, but for some, they remain a wardrobe staple.However, the term "jorts" has taken on a life of its own, particularly in the realm of college sports. It's become synonymous with a certain laid-back, irreverent style tied to the fans of the Florida Gators. As with many trends in fashion, the

The types of foods that we’re eating, and I’ll get to that in a minute. As long as we restrict the time period that we’re eating those foods, makes all the difference in the world. And, it’s a powerful tool to allow me and you to have some of the foods that we want to eat without worrying that, that’s going to have a profound negative impact on our health. So, let’s talk about some of the foods that people associate with energy boosting. And not a day goes by, you don’t see a TV commercial or something on the internet. That, protein increases your energy. Now, as I’ve talked about in the last two books, the energy paradox and Unlocking the Keto Code, let’s be clear about this. Energy is ATP. Adenosine triphosphate.(22:42):That’s our energy currency. And we know that ATP is produced by mitochondria. The little energy producing organelles in most of our cells. Mitochondria have to take protein, sugar, carbohydrates and fats and break them down to produce ATP. But if you’ve looked at either of those books or listened to them, you know that in our society, we bombard our mitochondria simultaneously with simple proteins, simple sugars and simple fats, that mitochondria were never designed to handle all at once. And living in the LA area that I do, we produce rush hour in our mitochondria, unfortunately 16 hours a day. And so, energy producing foods like protein for instance, may have actually the exact opposite effect on producing energy. Plus, be cautious. So many high protein drinks, so many high protein energy bars, also are high sugar. And the combo of simple broken down proteins and simple broken down sugars, is the perfect way to have gridlock in your mitochondria and actually have less energy, rather than more.(24:30):Another bomb is fruit smoothies. Now everybody knows, “Oh, fruit’s good for me. I’m going to have a fruit smoothie before my workout. It’s going to give me so much energy to get through my workout.” Well, as human studies have shown, breaking down fruit into simple fructose by using a smoothie, fructose is the number one way to impair our mitochondrial function in our liver. It actually lessens ATP production and increases fatty liver. And so, fruit smoothie is the last thing you want for energy. But Dr. Gundry, I have to have these things to get through my workout. Well, the exciting thing is, in human trials, exercising on an empty stomach, actually has you produce more ATP and get more benefit out of your program than if you ate beforehand. And I like to use the example of my mother and swimming in the summer.. How did mitochondria come about? The bacteria that originally used sunlight for energy evolved into chloroplasts.
