Second Messengers are Important in the Functioning Of

Question

Second messengers are important in the functioning of
A) nonsteroid hormones
B) steroid hormones
C) carbohydrate hormones
D) both b and c above

Accepted Answer

Second messengers are important for nonsteroid hormones such as epinephrine, adrenaline, and insulin, which cannot enter the cell membrane and require second messengers to mediate their effects. Steroid hormones, on the other hand, are able to enter the cell membrane and bind to intracellular receptors, bypassing the need for second messengers. Carbohydrate hormones are not a known category of hormones; glucose, for example, is not a hormone and does not require second messengers for its function.
