Transport dietary triglycerides. Taken to the liver by portal blood. The Postabsorptive State. The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (catabolism exceeds anabolism). The absorptive state of metabolism lasts for about four hours, during and after each meal. Which of the following statements regarding plasma cholesterol concentration and the development of atherosclerosis is correct? 56. 20. 60) During the absorptive state, A) skeletal muscle fibers release glucose. The anabolic effects of insulin are accomplished by: 40. 67. 39. In subjects with non insulin-dependent diabetes mellitus: E. Both insulin target tissues have fewer than normal or abnormal insulin receptors and increased exercise and caloric restriction generally improve their condition are correct, D. Both precursor of steroid hormones and component of plasma membranes are correct. Absorptive and Postabsorptive States The absorptive state is the time during and right after eating a meal. The liver will store … Insulin has no effect on the carrier-mediated transport of glucose in the liver; therefore, insulin does not stimulate the uptake of glucose by that organ. Anorexia nervosa is excessive thinness usually caused by hyperthyroidism. What factors affect the brain's control of food intake in a normal person? 61. During the absorptive state, the stomach and intestines contain nutrients that are being absorbed by the body. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The Postabsorptive State. They are degraded to free fatty acids(FFA) by lipoprotein lipase(LPL). Absorptive state starts immediately after the ingestion of foods. The major metabolic effects of glucagon include: A. Distinguish between the major characters of the absorptive and postabsorptive state in term of the conditions that establish the states and hormones that control the associated activities. When ketone bodies are present in the blood and urine in large amounts, it usually indicates increased metabolism of _____. The calorigenic effect of thyroid hormones refers to their effect in increasing the rate at which the body synthesizes protein and fat. The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (catabolism exceeds anabolism). Increases the uptake and utilization of glucose by muscle and adipose tissue cells. The absorptive state of metabolism lasts for about four hours, during and after each meal. 76. Most of the glucose stored after a high-carbohydrate meal is stored in the form of glycogen. The major metabolic effects of glucagon include: 22. 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. The excess NH4+ is converted to urea by the liver. The Postabsorptive State. ... builds up triglycerides during the postabsorptive state. Transports cholesterol to peripheral tissues. In summary, what happens to glucose during the absorptive phase? It is preferable to have a low LDL:HDL ratio because HDL operate to remove cholesterol from the peripheral tissues and carry it to the liver, which secretes it into the small intestine, 38. 1) Glycogen synthesis: converts glucose into glycogen (hydrated and bulky - can only store so much). 29. Your first task is to apply the mass balance equation to the maintenance of the glucose pool during the absorptive and postabsorptive states. 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. 73. Body mostly depends on glycogen stores. During the absorptive state of metabolism, amino acids: D. Both are used for protein synthesis in most body cells and are used for protein synthesis in the liver are correct. The chemoreceptors for the reflexes that stimulate sympathetic activity and epinephrine secretion in response to hypoglycemia are located in the carotid and aortic bodies. Are used for protein synthesis in most body cells B. The Postabsorptive State. 60) During the absorptive state, A) skeletal muscle fibers release glucose. An absorptive state occurs during the period within four hours of food consumption. Which one of the following terms best describes the reaction in the Kerbs cycle in which a molecule a) Pyruvic acid b) Glycogen c) Amino acids d) Insulin e) Glucase. causes a decline in circulating ketone bodies. 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. B) insulin levels are low. 47. 85. During this state, digestion of food and absorption of nutrients into blood take place. Discuss the metabolic reactions that occur for glucose, amino acids, and lipids that predominate during the absorptive state. PostabsorptiveState" "As"the"absorptive"state"comes"to"an"end,"enterocytes"stop"providing"glucose"to"the"hepatic" portal"circulation. Stimulated by insulin - promotes storage. macromolecules: Term. After absorbing nutrients in the intestines, blood then travels to: A. Which of the following tissues is most dependent upon a constant blood supply of glucose? In the post absorptive state, maintenance of steady-state concentrations of plasma amino acids depends on release of amino acids from tissue protein.After a meal, dietary amino acids enter the plasma, replenish the tissues and are metabolized during fasting. 68. 2. Key Points. 83. Quizlet 16 1. A. Estrogens. With regard to fat metabolism, insulin increases: D. Both the activity of lipoprotein lipase and triacylglycerol synthesis by increasing glucose transport into adipose tissue cells. The digestion of carbohydrates begins in the mouth, whereas the digestion of proteins and fats begins in the stomach and small intestine. Cholesterol or its derivatives are directly involved in each of the following except: 37. Metabolic acidosis caused by excessive blood levels of ketones is one of the most serious consequences of untreated insulin-dependent diabetes. ... builds up triglycerides during the postabsorptive state. In this state glucose concentration in the blood declines and hence insulin levels are also decreased. The energy used for doing work is incorporated into ATP. The liver which metabolizes many of the absorbed nutrients. 69. 26. The factor that increases metabolic rate to the greatest extent is increased: 45. Chylomicrons: formed in enterocytes during the absorptive phase only. In the liver, glucose is converted to glycogen or fat, which store energy for future use. 50. For each state, you need to explain how each of the parts of the equation contribute to increases/decreases in the glucose pool, and the internal mechanisms that are employed to counteract those changes to restore balance. Insulin is a satiety signal that suppresses appetite, whereas glucagon stimulates appetite. The most important of the glucose-counter regulatory controls in normal circumstances is epinephrine. 62. C) adipocytes release fatty acids to the circulation. 70. 42. 16. All other things being equal, a person who is hypothyroid will have a higher BMR than a person whose thyroid function is normal. Throughout this state, digested food is converted into sugar or glucose. When plasma glucose concentration increases, the secretion of insulin is ________ and the secretion of glucagon is ________. B. Liver glycogen is broken down to glucose, which is released into the blood, A. 65. B) insulin levels are low. In Addison's disease, the adrenal cortices degenerate. Untreated insulin-dependent diabetic subjects will die because of: E. Dehydration due to glycosuria and ketonuria, which causes reduced cerebral blood flow and acidosis due to excessive levels of plasma ketones, 32. During the absorptive state of metabolism, the primary energy source for most of the body's cells is ________, except for ________, which use ________ for energy. The metabolic adjustments that occur as the body switches between the postabsorptive and absorptive states are largely triggered by changes in the Definition plasma concentration of insulin, a peptide hormone secreted by beta cells located in the pancreatic islets of Langerhans The plasma glucose concentration is maintained surprisingly constant during the fasting, or postabsorptive, state because of the secretion of glucose from the liver. The reason high humidity plays such a significant role in increasing the discomfort felt on very hot days is that it decreases the cooling properties of conduction. 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). 18. If both are present in relatively high amounts, then the excess of insulin promotes the glucose conversion into glycogen for storage in the liver and muscle cells. 10. 82. It is transported in chylomicrons to adipose tissue for storage or to other tissues as fuel. Question: Part D Metabolism During The Absorptive State During The Absorptive State, Metabolism Adjusts To Either Provide Energy For Immediate Use Or Store Excess Energy To Be Used Later Drag The Appropriate Items Into Their Respective Bins. 48. The absorptive state lasts for four hours, during and after each meal. FFAs are transported into cells. The absorptive state lasts for four hours, during and after each meal. You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. During the absorptive state, the body makes use of stored nutrients for energy. Nutrients are absorbed from the GIT and stored, glucose is the primary energy source. 5. Primarily anabolic. Remnants are taken up by the liver or processed to LDL. During the absorptive state, the body digests food and absorbs the nutrients. These nutrients are used to meet the immediate energy needs of the body. During the absorptive state of metabolism: C. Lipoprotein lipase breaks down triacylglycerols in adipose tissue capillaries, C. Converted to monoglycerides and fatty acids by an enzyme in the capillaries. Most of the energy used by the body during fasting is provided by gluconeogenesis. 31. absorptive state. C) adipocytes release fatty acids to the circulation. Also during the absorptive state, chylomicrons, the product of fat digestion, are reconstituted to fat and stored in adipose tissue or, in a low carb environment, are used as an energy source. Converted to fat for energy or storage. During the absorptive state, there is net synthesis of fat, glycogen, and protein, but this process is reversed during the post absorptive state. Takes up glucose and stores it as glycogen. During stress, elevated levels of plasma cortisol stimulate the catabolism of muscle protein and the conversion of alpha-keto acids to glucose in the liver. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. Generally, what happens in the absorptive phase? 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 & oxidized for energy Is absorbed fatty acids to the maintenance of the glucose pool during the absorptive state, food...
