1 year ago. United States time now. The liver will store glucose or turn any excess glucose into body fat for storage. These glands produce the fluid component of se...

Once the nutrients in the stomach and intestines are exhausted, the body returns to a post-absorptive state during which energy needs are met by stored fuels contained in body tissue. The time of exercise relative to breakfast did not affect 24 h energy expenditure (P>0.5). The post–absorptive state lasts until 8 to 12 hours after your last meal, which is when you enter the fasted state.

Thanks!!! A post-absorptive state differs from an absorptive state. absorptive state: The period during digestion when anabolism exceeds catabolism. Insulin is a hormone that allows glucose to enter the cells and be used for energy. Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism.The fuel used for this process is glucose.. Nutrient processing in the absorptive state. Study Absorptive and Post Absorptive States flashcards from Christina Stafstrom's class online, or in Brainscape's iPhone or Android app. Simple. This phenomenon is due largely to greater lipid and lower carbohydrate availability, as plasma non-esterified fatty acid (NEFA) concentrations rise in response to lower insulin and higher counter-regulatory hormone concentrations. The plasma glucose concentration is maintained surprisingly constant during the fasting, or postabsorptive, state because of the secretion of glucose from the liver. The absorptive state lasts for four hours, during and after each meal. In fact, there are a lot of parallels between exercise and fasting. The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. Digestion begins the moment you put food into your mouth, as the food is broken down into its constituent parts to be absorbed through the intestine. This glucose is derived from the processes of glycogenolysis and gluconeogenesis, which are promoted by a high secretion of glucagon coupled with a low secretion of insulin. Strange Americana: Does Video Footage of Bigfoot Really Exist? What is the meaning of post-absorptive? Once fat reserves are depleted, the body begins to synthesize proteins from muscle tissue. describe the release of insulin-2 phases -Almost immediately after infusion, plasma insulin rises dramatically due to secretion of preformed insulin, this is soon depleted The primary aim of our study was to determine whether 24 h fat oxidation was affected by time of exercise relative to breakfast, i.e. When you're in the fasted state your body can burn fat that has been inaccessible during the fed state. Relationship between turnover rate and oxidation rate of alanine in the post-absorptive state and during parenteral nutrition before and after surgery. This video is updated from its earlier version. Results: During the 60 min of exercise, energy expenditure in the two exercise trials were equivalent, but exercise in the post-absorptive state was performed with lower RQ compared with that in the postprandial state (P<0.01).
