Figure 24.5.2 – Postabsorptive State: During the postabsorptive state, the body must rely on stored glycogen for energy, breaking down glycogen in the cells and releasing it to cell (muscle) or the body (liver). 14. 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. Glycogen is formed in the liver during the absorptive state. During fasting, post-absorptive state, fatty acid oxidation contributes proportionately more to energy expenditure than does carbohydrate oxidation. 47. Excess ketoacids can be converted to triacylglycerol in the liver. During the postabsorptive state, metabolism shifts to favor catabolic reactions. During the post absorptive state skeletal muscle glycogen contributes to Wood Glucose Directly by reduction of glycogen stores to glucose Directly by contribution of glycoger into Wood Indirectly by release of lactate to Iiver which contributes to formation of blood glucose Indirectly by release of glycerol which contributes to formation of Wood glucose.
