which of the following occurs during the absorptive state?

© copyright 2003-2021 Study.com. The Absorptive State The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (anabolism exceeds catabolism). The fuel used for this process is glucose. These nutrients are used to meet the immediate energy needs of the body. 12. False. The main components through which the nutrients can pass include the blood and lymph. Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism. The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). Excess ketoacids can be converted to triacylglycerol in … In the absorptive state, the nutrients entering the blood from the gastrointestinal tract are hexose sugars and amino acids. Blood glucose falls C. Fatty acids are oxidized for fuel D. Lipolysis is occurring E. Gluconeogenesis is suppressed Every living cell in a person's body has a metabolism, referred to as, Cell Metabolism. Which of the following options is correct? These take the nutrients to the specific cells where the metabolic activity takes place. Gluconeogenesis is a postabsorptive phenomenon. Start studying The absorptive state. Learn vocabulary, terms, and more with flashcards, games, and other study tools. All other trademarks and copyrights are the property of their respective owners. E.

A. Glucagon levels increase B. Beta oxidation _____ happens in the cytoplasm, whereas _____ happens in the mitochondrion. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. A. Want to see this answer and more? Glycolysis; the citric acid (Krebs) cycle. C. has gluconeogenesis as one of its main events. The absorptive state of metabolism lasts for about four hours, during and after each meal.

Throughout this state, digested food is converted into sugar or glucose. Trance is an altered state of consciousness characterized by a narrowed awareness of external surroundings. B. is when glycogenolysis usually occurs. as body progresses from absorptive to post absorptive state all other organs, besides __, switch to fatty acids as major energy source: brain: during transition phase, from absorptive to post absorptive state, __ begins in adipose tissues & released __ __ are picked up by tissue cells & … Which of the following occurs during the absorptive state? Which of the following occurs during the post-absorptive state (after food has been digested)? The constituent parts of these carbohydrates, fats, and proteins are tra… During the postabsorptive state, both glucose production and glucose conservation help maintain blood glucose level: Hepatocytes produce glucose molecules and export them into the blood, and other body cells switch from glucose to alternative fuels for ATP production to conserve scarce glucose. (Note: more than one answer may be correct). 2005). Metabolites are transformed to fat if they are not used for anabolism. B. Question options: glycogen. Gluconeogenesis is suppressed. The glycogen and fat will be stored in the liver and adipose tissue, respectively, as reserves for the post-absorptive state. During this state glucose is the most important energy fuel. Hypothermia may be fatal if the core body temperature reaches 37°C or lower. False. of energy storage molecules and other processses characteristic of the absorptive state : Term. 60) During the absorptive state, A) skeletal muscle fibers release glucose. True . During this state glucose is the most important energy fuel. Glucose is also carried in the bloodstream to cells where it will be used to provide energy for cellular processes. An absorptive state occurs during the period within four hours of food consumption. During this interval, transient increases in plasma glucose, amino acids, and triacylglycerols (TAG) occur, the latter primarily as components of chylomicrons synthesized by the intestinal mucosal cells (see p. 228).
