What You Should Have Gotten Out of the Metabolism Lecture or Learning Objectives for the Metabolism Lecture During the absorptive state, anabolism of fat and protein occurs, glycogen is stored and glucose is used for energy. During the postabsorptive state, glycogen is broken down, fat and protein catabolism occurs and glucose is spared for use by nervous tissue. 1. Define/describe metabolism, anabolism, catabolism. Define/describe absorptive and postabsorptive states. Describe what happens to carbohydrates during the absorptive state. Understand and describe how glucose is stored. Understand why glucose levels in the blood must be maintained. Describe how glucose levels are maintained in the postabsorptive state. Know the first line of defense against a drop in blood glucose. Define/describe gluconeogenesis. Describe glucose sparing. 2. Describe what happens with the other 2 major nutrients (fat, protein) during the postabsorptive and absorptive states. Know how excess food molecules are stored. Understand the figure that summarizes the events that occur in the absorptive state
