![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
