What is the correct to say about the hormone action in humans?

Options

A. Glucagon is secreted by `beta-`cells of islets of Langerhans and stimulated glycogenolysis.
B. Secretion of thymosin is stimulated with aging.
C. In females, FSH first binds with specific receptors on ovarian cell membrane.
D. FSH stimulates the secretion of androgens.

Answer

C

Explanation

Mechanism of hormone action is not the same in all categories of hormones. These hormones bind with the specific receptors located in their target tissues. Hormone receptor is of two types: membrane bound receptor and intracelular receptor. FSH is a proteinaceous hormone, has large molecular weight and is insoluble in lipids, therefore, it cannot enter the target cell . Thus, it binds with the membrane bound receptor present on ovarian cell membrane
