Synergism Occurs When

Synergism occurs when:

A) One hormone induces the loss of another hormone's receptors.
B) The actions of several hormones are complementary, and their combined effect is greater than the sum of their separate effects.
C) One hormone must be present in adequate amounts for the full exertion of another hormone's effect, even though the first hormone does not directly elicit the response.
D) One hormone increases the number of target-tissue receptors for another hormone.
E) The number of target tissue receptors for a hormone is reduced as a direct consequence of the hormone's effect on its own receptors.
