Question

Quizplus · Accepted Answer

cAMP is a common second messenger used by many hormones to activate cellular responses.

Answer: I
 Nonsteroid hormones are typically composed of proteins or amino acids and cannot pass through the cell membrane to affect the nucleus.

Answer: C
 Prostaglandins are lipid-based second messengers that mediate a variety of physiological responses.

Answer: D
 Target cells are the specific cells that a hormone binds to and affects.

Answer: E
 Up-regulation refers to an increase in the number of receptors on a target cell, allowing for a greater response to a particular hormone.

Answer: F
 Antagonism occurs when two hormones have opposing effects on a target cell.

Answer: H
 Tropic hormones are hormones that stimulate the release of another hormone.

Answer: B
 Steroid hormones are derived from cholesterol and can pass through the cell membrane to affect gene expression.

Answer: A
 Synergism occurs when two hormones work together to produce a greater effect than either hormone alone.

Answer: J
 Permissiveness occurs when one hormone is necessary for another hormone to exert its full effects.
