What kind of molecule is an enzyme?

Explanation:

An enzyme is a proteinous molecule that serves as a biological catalysts in living cells, regulating the rate of biochemical reactions. Like every other proteins, enzymes are made up of building blocks- amino acids, which are arranged in such a way that forms a specific 3D structure responsible for the specificity and functioning of that particular enzyme.

Enzymes catalyze a reaction by binding to the substrates or reactants of the reaction making the reaction faster due to its 3D shape. Enzymes are usually specific in their actions.
