Q

5 ways hormones can bring about change within a cell

A

Stimulating mitosis. Change membrane permeability. Synthesis of proteins. Activation of enzymes. Promotion of secretory activity.

25
Q

Direct gene activation

A

Diffuse through target cells plasma membrane. Enters nucleus. Binds to specific protein. Binds to specific site on cells DNA. activate genes causing synthesis.

26
Q

Second messenger system

A

Hormone binds to membrane receptor. Doesn’t enter cell. Causes reactions that activate enzymes. Catalyzes reaction to produce 2nd messenger molecule. Oversees additional intracellular changes to promote specific response.

27
