Which of the Following is Not True of a Nonsteroid

Question

Which of the following is not true of a nonsteroid hormone?
A) It is carried through the blood to the target organ cell.
B) Its receptor is in the nucleus of the target organ cell.
C) It requires a second messenger.
D) All of the above are true of nonsteroid hormones.

Accepted Answer

The receptor of nonsteroid hormones is typically found on the surface of the target cell and not in the nucleus. Steroid hormones, on the other hand, can pass through the cell membrane and bind directly to receptors in the nucleus.
