|
|
Term
|
Definition
•Diffuse through the plasma membrane of target cells
•Enter the nucleus
•Bind to a specific protein within the nucleus
•Bind to specific sites on the cell’s DNA
•Activate genes that result in synthesis of new proteins |
|
|
Term
Second-Messenger System (Nonsteroid Hormone Action) |
|
Definition
•Hormone binds to a membrane receptor
•Hormone does not enter the cell
•Sets off a series of reactions that activates an enzyme
•Catalyzes a reaction that produces a second- messenger molecule (such as cAMP)
•Oversees additional intracellular changes to promote a specific response |
|
|
Term
control of hormone release |
|
Definition
- A stimulus or low hormone levels in the blood triggers the release of more hormone
- Hormone release stops when appropriate level in blood is reached |
|
|
Term

|
Definition
|
|
Term
