Sample Question
What is growth hormone, where is it produced, and what is its primary role in regulating organism growth?

Growth hormone is a steroid hormone produced by the adrenal cortex that directly stimulates bone elongation by binding receptors on osteoblasts in growth plates

Growth hormone is a peptide hormone produced by the thyroid gland that regulates metabolic rate and indirectly influences growth by controlling energy availability

Growth hormone is a neuropeptide released from the hypothalamus that acts directly on muscle tissue to increase fiber diameter through activation of satellite cell proliferation

Growth hormone is a peptide hormone secreted by the anterior pituitary gland that stimulates skeletal growth, protein synthesis, fat mobilization, and carbohydrate metabolism, with many of its growth-promoting effects mediated indirectly through IGF-1
