The following question(s) are based on the reaction A + B ↔ C + D shown in the accompanying figure.
-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) vaccination
B) denaturation
C) allosteric regulation
D) competitive inhibition

Quizplus · Accepted Answer

The strategy of finding drugs that fit into the active site of HIV protease to block it is an example of competitive inhibition, as the drug molecules are competing with the substrate molecules for binding to the active site.
