15.18) Determine whether the following statements describe insulin, glucagon, or both insulin and glucagon. a) secreted by pancreas both insulin and glucagon b) released when blood glucose concentration is high insulin c) released when blood glucose concentration is low glucagon d) immediately increases the amount of glucose entering cells insulin e) is a hormone both insulin and glucagon f) lowers blood glucose concentration insulin g) not enough is produced by individuals with type-1 diabetes insulin h) stimulates glycogen breakdown (glycogenolysis) glucagon EXPLANATION: When insulin binds to liver and muscle cell receptors, it triggers a series of events that result in the activation of an enzyme in the glycogenesis pathway and the inhibition of an enzyme in the glycogenolysis pathway. Glucagon has the opposite effect of insulin on liver cells; it accelerates glycogenolysis and suppresses glycogenesis causes a decrease in blood glucose levels accelerated by insulin • suppressed by glucagon glucose glycogenesis glycogen glycogenolysis causes an increase in blood glucose levels accelerated by glucagon • suppressed by insulin
