Question

hormonal interactions
what does permissiveness in hormonal interactions refer to?
one hormone allowing another hormone to exert its full effect
one hormone inhibiting the activity of another hormone
hormones working together to enhance their effects
hormones acting independently without influencing each other

Explanation:

To determine the correct answer, we analyze the concept of permissiveness in hormonal interactions:

• The first option ("One hormone allowing another hormone to exert its full effect") matches the definition of permissiveness, where one hormone enables another to act fully (e.g., thyroid hormone permitting epinephrine's effects on fat breakdown).
• The second option describes antagonism (one hormone inhibiting another).
• The third option describes synergism (hormones working together to enhance effects).
• The fourth option describes independent action, which is not permissiveness.

Answer:

A. One hormone allowing another hormone to exert its full effect
