Quizplus · Accepted Answer

Steroid hormones use the mobile receptor model to function.

 Target cell is the cell that has a specific receptor for a hormone and is affected by the hormone.

Answer: C
 Second messengers are intracellular molecules that transmit signals from the hormone receptor to the cellular response.

Answer: I
 Nonsteroid hormones use the membrane-bound receptor model to function.

Answer: E
 Up-regulation is the increase in the number of hormone receptors on a target cell, resulting in increased sensitivity to the hormone.

Answer: F
 Antagonism is when one hormone opposes the actions of another hormone.

Answer: G
 Prostaglandins are hormone-like substances that have a variety of physiological functions.

Answer: H
 Tropic hormones are hormones that stimulate other endocrine glands to release hormones.
