Which hormone prevents hypoglycemia by promoting the conversion of glycogen to glucose (glycogenolysis) and the conversion of protein to glucose (gluconeogenesis)?
A. Testosterone
B. Somatostatin
C. Glucagon
D. Insulin
C
Glucagon increases or maintains blood glucose levels. Glucagon is stimulated by a decrease in blood glucose levels and an increase in blood amino acid levels. In the liver, the primary target organ of glucagon, glucagon causes glycogenolysis (the conversion of glycogen to glucose). In addition, glucagon enhances amino acid transport from muscle and promotes gluconeogenesis (the conversion of amino acids to glucose).
