Contrast the metabolic events of the absorptive versus the postabsorptive states
What will be an ideal response?
During the absorptive states, the body is absorbing nutrients and utilizing glucose as its major energy source. Very little of the absorbed fat and amino acids are used at this time because most cells use glucose when it is available (and adequate insulin is available). Extra nutrients not immediately used for energy or structural repairs are stored as glycogen or triglycerides. During the postabsorptive states, energy stores are mobilized and gluconeogenesis and glucose-sparing maintain the blood glucose at an adequate level to nourish the brain.
