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

Explanation:

If the strategy of using a drug that binds to the active site of the enzyme and block it proves successful, then the phenomenon taking place is :

D. Competitive inhibition.

A competitive inhibitor of an enzyme is a molecule that closely resembles the substrate and binds to the active site of the enzyme and blocks its . Competitive inhibition is a reversible phenomena and it can be reversed by increasing the substrate concentration.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
