blood glucose is initially decreasing.b. 20. Chronic insulin and glucagon deficiencies have been proven to cause hyperglycemia and, therefore, suggesting that insulin is the predominant factor of postabsorptive glucose levels. During the absorptive (fed) phase of metabolism, plasma levels of which of the following substances would be expected to be less than normal? Which hormones change in response to low glucose levels? post-absorptive state: The metabolic state achieved after complete digestion and absorption of a meal. A number of nutrients in the blood can stimulate its release. Welcome to Sciemce, where you can ask questions and receive answers from other members of the community. macromolecules: Term. Insulin doesn’t simply control blood sugar. During the absorptive state, glucose levels are _____, insulin levels are _____, and glucagon levels _____. Ch. During the absorptive state, energy is stored in: Definition. The absorptive state of metabolism lasts for about four hours, during and after each meal. During the absorptive state, a. breakdown of glycogen supplies glucose to the blood. The metabolic adjustments that occur as the body switches between the postabsorptive and absorptive states are largely triggered by changes in the: Definition. The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. Insulin promotes the synthesis: Definition. 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). absorptive state: also called the fed state; the metabolic state occurring during the first few hours after ingesting food in which the body is digesting food and absorbing the nutrients glycogen form that glucose assumes when it is stored. The metabolic adjustments that occur in the body during the switch from postabsorptive to absorptive state are largely triggered by increases in _____ concentration. Soon after a meal, glucose-dependent insulinotropic peptide (GIP), plus the rising blood levels of glucose and certain amino acids, stimulates pancreatic beta cells to release insulin. 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). In the nonstressed, fasted or post‐absorptive state, the level of glycemia is regulated by the glucose output from the liver, and the metabolic substrate is mainly FFA. Absorptive state: The absorptive state is referred to as the time after a meal during which the absorption of nutrients takes place. The liver will store glucose or turn any excess glucose into body fat for storage. Both are then released into the blood, where they serve directly as an energy source (fatty acids) or as a gluconeogenic precursor (glycerol). During this absorptive state glucose is used by many tissues for energy metabolism. INSULIN. absorptive state kicks in your body, especially after you've eaten a substantial meal. In the absorptive state, insulin is the main hormone that helps in providing glucose for cellular consumption and storage. glucagon is released.c. The absorptive (fed) state is characterized by which of the following? Insulin promotes glycogen synthesis in liver and muscle. Insulin also stimulates lipogenesis. Despite evidence that the PNS remains activated during the absorptive phase of the meal, its role in mediating postprandial insulin secretion has not been established. The Jews are broken down to make energy in the cell. Insulin stimulates glycogenosis in the liver as well, so glucose is first stored as glycogen Glucose-->G6P-->G1P-->Glycogen. Postabsorptive state or fasting state is the time that starts after the completion of nutrient absorption. 0 votes. What is Postabsorptive State? Best answer. Not surprisingly, insulin inhibits the activity of HSL during the absorptive state, because it would not be beneficial to break down stored fat when the blood is receiving nutrients from ingested food. Insulin is released from the beta cells of the pancreas after intake of food. hormone. During the absorptive state, insulin release is. Insulin rises significantly, completely shutting off fat-burning and also triggering excess calories to be stored as fat. The elevated insulin-to-glucagon ratio and the ready availability of circulating substrates make the absorptive state an anabolic period characterized by increased synthesis of TAG and glycogen to replenish fuel stores and enhanced synthesis of protein. B. stimulated. Because of decreasing blood glucose levels, there is a shift in the tissue energy metabolism from cars to fatty acids, as the body enters the postabsorptive state, which occurs about four hours after a meal and continues until the next meal. a. insulin b. glucose insulinotropic peptide c. very low density lipoprotein (VLDL) d. glucagon . Correct answer Welcome to Sciemce, where you can ask questions and receive answers from other members of the community. 24 - Discuss how carbohydrates can be stored as fat. Regulation of Metabolism during the Absorptive State. The postprandial state generally lasts three to five hours after eating a meal. That gets coupled w/ FAs and is transported to adipose tissue via VLDLs. Chapter 16: Metabolism, insulin & glucagon . In addition, any increase in glucose that occurs during the absorptive phase of digestion cannot be blunted by insulin release, which contributes to postprandial hyperglycemia. Injection of basal insulin to mimic insulin normally produced during the post-absorptive state is usually accomplished by utilizing a long-acting insulin, such as ultralente, or an intermediate-acting insulin, such as NPH. 24 - Insulin is released when food is ingested and... Ch. 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. It seems that one of the metabolic problems during sepsis is an inability to use FFA as a metabolic substrate. However, glucose is the most important one. During the absorptive (fed) state: (check all that apply) the liver forms glycogen insulin levels are elevated skeletal muscle breaks down glycogen adipocytes release fatty acids to the circulation High levels of glucose and amino acids in the blood (as when a meal is being processed) are the primary stimuli for insulin secretion. Insulin is a hormone that allows glucose to enter the cells and be used for energy. About four hours after the meal is known as the absorptive state. Insulin regulates the rate of glucose uptake by nearly all cells except neurons, kidney cells, and erythrocytes, which have an independent rate of uptake. After the first few hours mentioned above, your body goes into what is known as the post–absorptive state, during which the components of the last meal are still in the circulation. And we also know that when glucose is high, you need to keep your blood glucose level balance and not have that spike too much. The three major target tissues for insulin are the liver, muscle, and adipose tissue, as shown in Figure 12.2. The release of insulin into the blood is stimulated by eating and inhibited by fasting, and insulin is largely responsible for promoting the pattern of metabolism seen in the absorptive state. Answer to During the absorptive statea. The hormones that regulate postabsorptive state metabolism sometimes are called anti-insulin hormones because they counter the effects of insulin during the absorptive state.
