1. C Up-regulation A. Chemical signals within a cell that mediate the action of a
water soluble hormone or other chemical.
2. E Permissive effect B. Water-soluble hormone or other chemical that binds to
receptors in plasma membranes.
3. D Down- Regulation C. Increased numbers or affinity of hormone receptors in
response to low hormone concentration
4. B First Messenger D. Decreased numbers or affinity of hormone receptors in
response to high hormone concentration.
5. A Second Messenger E. Hormone-induced changes that facilitate the maximal
response or functioning of a cell.
