C) adipocytes release fatty acids to the circulation. The excretion of glucose in the urine of a diabetic patient is a result of the inability of the kidney tubules to reabsorb glucose in the absence of insulin. Promoting glycogenolysis and gluconeogenesis in the liver. 1) Used as a primary energy source (CNS, RBCs). Role of Organs in Amino Acid Metabolism. 65. A. Estrogens. Discuss the metabolic reactions that occur for glucose, amino acids, and lipids that predominate during the absorptive state. 14. 1) Glycogen synthesis: converts glucose into glycogen (hydrated and bulky - can only store so much). The liver will store … 24. 15. Excess absorbed glucose is initially converted to triacylglycerides and very low density lipoprotein by: 9. Throughout this state, digested food is converted into sugar or glucose. If more calories are ingested in food than are expended by metabolism. Start studying endocrine physiology part 3. C) adipocytes release fatty acids to the circulation. Start studying Nutrition test 2. Carbohydrates - Simple sugars are sent to the liver where they are converted to glucose.The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). The Post absorptive state is also known as fasting state. 33. 48. PostabsorptiveState" "As"the"absorptive"state"comes"to"an"end,"enterocytes"stop"providing"glucose"to"the"hepatic" portal"circulation. 46. The factor that increases metabolic rate to the greatest extent is increased: 45. The rest of the absorbed glucose is used to provide stores of energy for later use during the post-absorptive (fasting) state (see below). Catabolic hormones or conditions include the following: A. Elevated plasma cortisol concentration, A. Elevated plasma cortisol concentration, B. Most of the energy used by the body during fasting is provided by gluconeogenesis. Key Points. 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. 30. Start studying Chapter 24: Metabolism & Nutrition. 66. Carbs/proteins are taken to the portal vein and then to the liver. Anorexia nervosa is excessive thinness usually caused by hyperthyroidism. 12. The major metabolic effects of glucagon include: A. The constituent parts of these carbohydrates, fats, and proteins are tra… FFAs are transported into cells. 72. macromolecules: Term. Both IDDM and NIDDM subjects will experience increased appetite because: C. Specific appetite/satiety centers in the hypothalamus are not able to obtain enough glucose, C. The environmental temperature at which the body can regulate core temperature without either increasing or decreasing heat production. 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. Medical definition of absorptive: relating to or functioning in absorption. Symptoms of untreated insulin-dependent diabetes mellitus include: D. Hyperglycemia and reduced blood volume. The most important of the glucose-counter regulatory controls in normal circumstances is epinephrine. When you eat, your body uses this food to fuel the cells. The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. However, an increase in sympathetic activity will cause ________ secretion of insulin and ________ secretion of glucagon. During the absorptive state, glucose is the main fuel for most tissues of the body, which utilize it by glycolysis, the citric acid cycle and other pathways. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. Meanwhile, the postabsorptive state starts after the complete absorption of nutrients. Excess is deaminated to ketoacids which are then used as fuel or converted to glucose/glycogen/fat. During the absorptive state, the body digests food and absorbs the nutrients. 4. They are degraded to free fatty acids(FFA) by lipoprotein lipase(LPL). 10. 28. 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. The plasma glucose concentration is maintained surprisingly constant during the fasting, or postabsorptive, state because of the secretion of glucose from the liver. Fatty acids released by lipolysis of triacylglycerol in adipose tissue travel in the plasma as VLDL. There is a substantial reduction in blood glucose concentration compared to the absorptive state. 58. 50. Excessive carbohydrate is also converted to lipid in the … What does the liver do during the absorptive phase? 81. The major energy sources for non-nervous tissue during the postabsorptive period are fatty acids and ketones. During exercise, glucose uptake by muscle cells is increased because of increased insulin secretion. Which one of the following terms best describes the reaction in the Kerbs cycle in which a molecule 13. During this state, the body must rely initially on … Which of the following does not characterize the postabsorptive state? 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. 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. 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.
