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 fuel used for this process is glucose. 121) 122) The metabolic rate while sleeping is higher than the basal metabolic rate. 2. what does the liver do? What is the difference between the absorptive and the post absorptive state? *most energy is derived from carbs at this time* How is energy stored? 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). 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. period when the metabolic rate is lowest. 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. There are metabolic pathways which form a two-part process; the first part is the one mentioned called, 'Catabolism,' during which the body processes food to use … postabsorptive state. The liver will store glucose or turn any excess glucose into body fat for storage. describe the features of GLUT 2 transporter, -High capacity but low affinity and thus functions as "glucose sensor" in pancreatic beta cells.
