Assertion (A). Hormones interacting with cell surface receptors do not enter the target but they generate second messenger
Reason (R ). Glucocorticoids bind to intracellular receptors and regulate gene expression

Hormones which interact with the membrane - bound receptors normally do not enter the target cell but generate second messengers. These second messengers are referred as

Hormones which interact with the membrane - bound receptors normally do not enter the target cell but generate second messengers. These second messengers are referred as

Assertion: Hormones which interact with membrane- bound receptor, enter the target cell and generate the secondary messengers that regulates cellular metabolism. Reason: Estrogen have the membrane bound receptor.
