Answer 1

Answer:

please mark me as brainliest

Explanation:

Enzymes are biological catalysts composed of amino acids; that is, they are proteins. Enzymes have a very specific three-dimensional shape, which includes a site for binding its substrate (called the active site) and sites (called allosteric sites) for binding cofactors, metals, coenzymes, or other small molecules that regulate the activity of the enzyme. Many cellular enzymes are multi-subunit proteins consisting of more than one polypeptide chain. Without enzymes acting as catalysts, very few metabolic chemical reactions would take place at a sufficient rate at body temperature to sustain life.
