Zoology-Hormone Action Mechanism

NEET Zoology Hormone Action Mechanism MCQ Question

Type: MCQ-conceptual-Easy-Class 11

Which of the following statements about hormone action mechanisms is correct?

A

Peptide hormones generate second messengers and do not enter target cells.

B

Steroid hormones act strictly on membrane-bound receptors.

C

All hormones interact with intracellular receptors to regulate gene expression.

D

Hormones that generate second messengers include glucocorticoids.

Correct Answer

Option A

Detailed Explanation

Peptide hormones, such as insulin and glucagon, interact with membrane-bound receptors, leading to the generation of second messengers like cyclic AMP, rather than entering the target cell. Steroid hormones, on the other hand, typically enter the cell and interact with intracellular receptors to regulate gene expression.
