Question

which stimulates the secretion of growth hormone?

multiple choice

waking from sleep

exercise

increased levels of igf-i in blood

high plasma glucose

increased somatostatin secretion

Explanation:

Exercise is a known stimulator of growth hormone secretion. When the body engages in physical activity, it triggers physiological responses that lead to an increase in growth hormone release. Waking from sleep does not directly stimulate growth hormone secretion in the way exercise does. Increased levels of IGF - I (insulin - like growth factor - I) in the blood actually act as a negative feedback mechanism to inhibit growth hormone secretion. High plasma glucose levels also do not stimulate growth hormone; in fact, growth hormone has effects on glucose metabolism but high glucose is not a stimulant for its secretion. Increased somatostatin secretion inhibits growth hormone release.

Answer:

Exercise
