Answer:
Enzyme/substrate specificity.
Step-by-step explanation:
Enzymes are known as biological catalyst. They accelerate the rate of reaction by reducing the activation energy of the reactant in the cell. All enzymes are known as specialized proteins with definite structural confirmations.
Enzyme specificity: Specificity is defined as the ability of an enzyme to choose exact substrate from a group of same chemical molecules. It is known as molecular recognition mechanism, and it operates through the conformational and structural complementary between the substrates and the enzyme. Enzyme shows different-different types of specificity towards their substrate.
