Progestins, Androgens, and Estrogens

Question

Progestins, androgens, and estrogens
A) are chemically derived from cholesterol.
B) are peptide hormones.
C) are rigidly determined by sex.
D) bind to receptors on the cell membrane.

Accepted Answer

Progestins, androgens, and estrogens are steroid hormones, which are synthesized from cholesterol. They are not peptide hormones, their actions are not rigidly determined by sex (as they play roles in both males and females), and they typically exert their effects by entering cells and binding to intracellular receptors, not just receptors on the cell membrane.
