HIV is the virus that causes AIDS. In the mid-1990s, researchers discovered an enzyme in HIV called protease. Once the enzyme's structure was known, researchers began looking for drugs that would fit into the active site and block it. If this strategy for stopping HIV infections were successful, it would be an example of what phenomenon?
A) noncompetitive inhibition
B) denaturation
C) allosteric regulation
D) competitive inhibition

This strategy for stopping HIV infections by looking for drugs that fit into the active site and block protease would be an example of competitive inhibition, where the inhibitor competes with the substrate for binding to the active site of the enzyme.
