The high levels of glucose in the absorptive state stimulate the pancreas to release insulin, which lowers the blood glucose levels. This state is typically reached four or more hours after food has been consumed, usually overnight and in the morning before breakfast. Thus, the main metabolic challenge during the postabsorptive state is to maintain the normal blood glucose level of 70-110 mg/ 100 mL (3.9-6.1 mmol/liter). 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. About 50% of the glucose absorbed from a meal is oxidized by cells throughout the body to produce ATP via glycolysis, the Krebs cycle, and ETC. True or false the body experiences two metabolic states: the absorptive state is the period immediately after a meal, when nutrients are taken in through the intestinal wall into the circulatory and lymphatic systems. The absorptive state of metabolism lasts for about four hours, during and after each meal. So, this state starts immediately after the food ingestion. During the absorptive state, our body digests foods and absorbs nutrients into the blood. Excess ketoacids can be converted to triacylglycerol in the liver. lactic acid. Following a glucose load, the body assumes an absorptive state, and its metabolic profile is primarily regulated by insulin. During the absorptive state, anabolic processes use glucose in a variety of ways. To ensure the best experience, please update your browser. fatty acids. 9.1) and converted to ketoacids that are oxidized via the citric acid cycle and other pathways. 24.7 Metabolic states of the body Energy is stored in the absorptive state and released in the postabsorptive state Explain the concept of amino acid or carbohydrate-fat pools, and describe pathways by which substances in these pools can be interconverted. Hormonal Regulation of Metabolism in the Absorptive State, -4 hrs after a meal, abortion is nearly complete, blood glucose level starts to fall b/c glucose continues to leave bloodstream & enter body cells (while none is being absorbed in GI tract). Simple sugars are sent to the liver where they are converted to glucose. Not all terms will be used. absorptive state.
