D Correct answer
Explanation

Lipids do not functions as enzymes.The function of proteins as enzymes is perhaps their best-known function. Enzymes are catalysts—they initiate a reaction between themselves and another protein, working on the molecule to change it in some way.The enzyme, however, is itself unchanged at the end of the reaction.Enzymes are responsible for catalyzing reactions in processes such as metabolism, DNA replication, and digestion.
