Problem 25Multiple Choice

You must create a two-paragraph explanation synthesizing how insulin and glucagon coordinate during the transition from the fed to the fasted state over 12 hours. Which key points must you include to accurately portray their coordinated roles?

Include: insulin permanently shuts down hepatic metabolism after eating, so glucagon only acts in muscle to produce glucose, which is the primary mechanism maintaining blood glucose overnight.

Include: insulin and glucagon both rising together after a meal to accelerate both storage and release of glucose simultaneously, leading to rapid oscillation of blood glucose without a dominant state.

Include: postprandial insulin dominance that increases glucose uptake (muscle/adipose), glycogenesis and lipogenesis to store excess; gradual fall in insulin with rising glucagon during fasting, switching liver to glycogenolysis then gluconeogenesis and adipose to lipolysis to supply glucose and energy — the hormones reciprocally regulate to maintain euglycemia.

Include: the pituitary gland as the main source of insulin and glucagon and state that insulin activates gluconeogenesis while glucagon activates glycogenesis, which is the core coordination during fed-to-fasted transition.
