Question

Identify the correct statement from the statements given below ?

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

Answer 1

Answer: (C)

In females, FSH first binds with specific receptors on ovarian cell membrane

SOLUTION

Glucagon is secreted by alpha cells of islets of Langerhans and stimulates glycogenolysis i.e, breakdown of glycogen into glucose. Thymosin hormone secreted from thymus gland which stimulates the development of certain kinds of white blood cells involved in producing immunity. It also hastens the attainment of sexual maturity. In women FSH hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle stimulating hormone acts on the sertoli cells of the testes to stimulate sperm production. So, the correct answer is option C.
