Both catabolic and anabolic reactions are regulated by hormones. When the endocrine system detects a change in the concentration of nutrients, such as glucose levels dropping below normal, hormones are released to activate or deactivate the enzymes in the metabolic pathways. Which of the following statements is correct regarding the hormonal control of catabolism during the absorptive state?
a. Cortisol from the adrenal glands strimulates protein synthesis, gluconeogenesis, and lipolysis
b. Epinephrine from the adrenal glands stimulates glycogen synthesis and protein degradation, but it has little to no effect on lipid metabolism
c. Glucagon from the pancreas stimulates protein degradation, glycogenolysis, and lipolysis when blood glucose levels are low
d. Insulin released from the pancreas stimulates glycogenolysis and lipolysis, but has little effect on protein metabolism
Ans: c. Glucagon from the pancreas stimulates protein degradation, glycogenolysis, and lipolysis when blood glucose levels are low
