All drugs must interact specifically with a biological macromolecule to produce biological action؟ T /F

True

Explanation:

A drug is "a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body"(Oxford dictionary).

In the body, there are numerous macromolecules that perform various functions. These macromolecules often function as the target molecules to which different drugs may be bound.

A drug functions by binding strongly to a macromolecule with which it interacts in order to produce the desired biological action.
