- Diffusible: moves in and out of cells - Low cell density, gradient favors movement (AI) out - High cell density, gradient favors movement (AI) in and genes are activated - LuxR: protein, transcription factor, binds autoinducer to the promoter region of the operon - When the LuxR binds to the promoter region of the operon, then the luciferase enzyme can get made and genes are activated - Benefit: protective niche (Vibrio), squid (protection from predators) O2, CO2, and H2S are absorbed through the gill plume and transported to the blood cells of the trophosome (packed with bacteria). H2S is bound to the worm's hemoglobin and carried to the endosymbiont bacteria. The bacteria oxidize the H2S and use some of the released energy to fix CO2, in the calvin cycle. Some of the reduced carbon compounds synthesized by the endosymbiont are translocated to the animal's tissues - Sexual: zygospores - Asexual: sporangiospores - Requires compatible strains of opposite mating types. When the 2 mating strains are close, each produces a different hormone, called a pheromone, that causes their hyphae to form projections called progamtangia; these mature into gametangia. After fusion of the gametang Continue reading >>

    I am just starting the Atkin's diet again. I am in my third day of the induction diet, and I was feeling terrible earlier today. Has anyone experienced excessive sweating while on the diet? I was extremely hot at work today and sweating when none of my co-workers were. This only happened for about 2 hours and I am fine again. No, I am not going through menopause (only 35 years old). Thanks.

    For the first month or so, I was sweating as if I was in the jungle or something (although Chicago in July is not far from it!!). I chalked it up to an increase in my metabolism that came with the diet.. Since getting into OWL, this has been much less of a problem and things have stabilized although this has still been a much tougher summer than usual for dealing with the heat.

  3. Suzieplump

    Thanks for the reply. I thought maybe I was the only person who experienced sweating. I have been exercising on this diet too, so I did think that maybe my body was adjusting to everything. I do feel great right now though. I haven't wieghed myself, but I think that I have lost quite a bit of weight in these first three days. My clothes fit more loosely now. I am afraid to weigh myself, because the scale seems to discourage me!!! I hope I can stick to this new way of eating because I have a tendency to go back to my old habits. This will be a challenge for me, but I must say that I do feel good now.

Sort Proteins: makes nonessential AA that are in short supply. Removes excess AA & converts them to other AA, or deaminates them & converts them to glucose or fatty acids. Removes ammonia from blood & converts it to urea for excretion. Makes DNA/RNA. & many proteins. >> Other: Detoxifies alcohol, drugs, poison, & excretes them. Helps dismantle old RBC's & captures the iron for recycling. Stores most vitamins, & many minerals. Activates Vitamin D. AA: Before entering metabolic pathways, AA are deaminated (lose their nitrogen amino group). deamination produces ammonia (which provides nitrogen to make nonessential AA. Remaining ammonia is excreted by urea in liver/kid. AA pathway: can enter pathways as pyruvate/Acetyl CoA/others enter krebs as compounds other than Acetyl CoA. AA that make glucose either by pyruvate or krebs cycle are glucogenic. AA that are degraded to Acetyl CoA are Ketogenic. Thus, proteins unlike fats, are a good source of glucose when carbs aren't available. In the liver: because of capillary network the liver is first to get alcohol saturated blood. liver cells are the only other cells in the body that can make sufficient quantities of dehydrogenase, to oxidize a Continue reading >>

    (edit: it's worth pointing out that "Ketosis " on it's own is not a bad thing, but Diabetic ketoacidosis is. I assume this is the point of the question)
    Diabetic Ketoacidosis comes from High (hyper) Blood Sugar not Low (Hypo). They could happen together, if you had high blood sugar for too long, the Ketoacidosis happened then you over treated the high and it went low. In this case you'd have 2 separate problems. Hypoglaycemia and Ketoacidosis. Low blood sugar will make you pass out and go into a coma eventually. Ketoacidosis is very painful and horrible to be part of. But I wouldn't say they increase each others danger very much.

    I'm not a doctor, but from what I know of diabetic conditions, both of these can be dangerous, and especially if they occur together (especially since ketosis would probably indicate serious hypoglycemia).

What is ENERGY BAR? What does ENERGY BAR mean?ENERGY BAR meaning - ENERGY BAR definition - ENERGY BAR explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6Uu... Energy bars are supplemental bars containing cereals and other high energy foods targeted at people who require quick energy but do not have time for a meal. They are different from energy drinks, which contain caffeine, whereas bars provide food energy. Energy in food comes from three sources: fat, protein, and carbohydrates. A typical energy bar weighs between 45 and 80 g and is likely to supply about 200300 Cal (8401,300 kJ), 39 g of fat, 715 g of protein, and 2040 g of carbohydrates. In order to provide energy quickly, most of the carbohydrates are various types of sugars like fructose, glucose, maltodextrin, dextrose and others in various ratios. Use of complex carbohydrate sources like oats and barley is limited and such carbohydrate sources are mostly used in protein bars. Proteins come mostly in the form of fast digesting whey protein. Energy bars generally don't contain sugar alcohols, since these bars, due to type of carbohydrate content, don't require low calorie sweeteners to improve their taste. Fats in energy bars are kept to minimum and their main sources are often cocoa butter and dark chocolate. Energy bars are used as energy source during athletic events like marathon, triathlon and other events and outdoor activities, where energy expenditure is high, for longer period of time.

Energy Metabolism

Sort Electron Transport Chain The electron transport chain is the final pathway in energy metabolism that transports electrons from hydrogen to oxygen and captures the energy released in the bonds of ATP (respiratory chain). The electron transport chain captures energy in the high-energy bonds of ATP. The electron transport chain consists of a series of proteins that serve as electron "carriers." These carriers are mounted in sequence on the inner membrane of the mitochondria. The electron carriers pass the electrons down until they reach oxygen. Oxygen accepts the electrons and combines with hydrogen atoms to form water. Oxygen must be available for energy metabolism. As electrons are passed from carrier to carrier, hydrogen ions are pumped across the membrane to the outer compartment of the mitochondria. The rush of hydrogen ions back into the inner compartment powers the synthesis of ATP (energy is captured in the bonds of ATP). The ATP leaves the mitochondria and enters the cytoplasm, where it can be used for energy. Anaerobic When the body needs energy quickly, pyruvate is converted to lactate. The breakdown of glucose-to-pyruvate-to-lactate proceeds without oxygen-it is anaer Continue reading >>

    I'm on a ketogenic diet and have stopped taking protein shakes (excepting post-workout protein powder with water) because I've heard that it may cause an insulin spike. Is it true that protein powder with water will knock you out of ketosis? The one I'm using in particular is Optimum Nutrition Gold Standard 100% Whey.

  2. MattyP

    Yes it can.
    Protein is made up of seven different aminos, some of which (just as j.rightly correctly pointed out) can knock you out of ketosis because they are broken down into glucose in your blood.
    j.rightly is corrct. Do some research and it will confirm that protein can knock you out of keto. Anyone who says it can't doesn't understand the science behind it.
    That is why you are meant to eat about 65% of your diet from fats, 30% protein and no more than about 5% carbs (which will be incidental from your fat & protein based meals) to be sure you stay in ketosis.

  3. JoJo

    No.
    Ketosis is the deprivation of carbs. High end protein shakes, such as your ON Gold, don't contain many carbs. Thus, drinking your protein shake won't remove you from your ketogenic state. On the other hand, cheap proteins (Muscle Milk) and any protein labeled as "mass builder" will contain carbs to prevent ketosis.
    Your comment about protein shakes spiking insulin is wrong. Insulin is secreted to process sugar. Your ON Gold with water has hardly any sugar. Thus, drinking your protein shake will not spike your insulin. Insulin spikes usually only occur when you eat simple carbs from fruit, candy, etc...
