Inhibin secreted by granulosa cells selectively inhibits secretion of fsh by the pituitary
a. true
b. false

The correct answer will be option-true.

Explanation:

Follicular stimulatory hormone or FSH and inhibin are the complex proteins which play a various biological role in the reproductive system.

The FSH stimulates the secretion of inhibin from the gonads in both males (Sertoli cells) and females (granulosa layer). The production of inhibin suppresses the secretion of FSH from the pituitary gland.

The suppression of FSH directly suppresses the secretion of further inhibin and thus, option-true is the correct answer.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
