HUMAN NUTRITION

Detailed explanation-1: -Each enzyme only has 1 substrate that will fit its active site. What is this called? Reusablility.

Detailed explanation-2: -However, not all enzymes act only on a single substrate – substrate specificity is quite variable. Enzymes have usually evolved to catalyze one reaction, or a particular class of reaction, and the level of specificity will depend on the function of the particular enzyme.

Detailed explanation-3: -The ability of an enzyme to select a specific substrate from a range of chemically similar compounds is known as specificity. Since the enzyme and substrate exhibit complementary structural and conformational properties, specificity is a molecular identification process.
