Q. What is correct to say about the hormone action in humans ?
A) FSH stimulates the secretion of estrogen and progesterone
B) Glucagon is secreted by β-cells of Islets of Langerhans and stimulates glycogenolysis
C) Secretion of thymosins is stimulated with aging
D) In females, FSH first binds with specific receptors on ovarian cell membrane
Explanation
[Solution from source] FSH is a glycoprotein hormone, so in females it first binds to specific receptors on the membrane of ovarian cells. FSH stimulates follicle growth and oestrogen secretion but not progesterone, glucagon comes from α-cells (not β-cells), and thymosin secretion falls with age. Answer (4).
