What is an emzyme.

An enzyme is a biomolecule that acts as a catalyst to speed up specific chemical reactions. Enzymes are either proteins or RNA molecules . Proteins are one of the major biomolecules; the others are carbohydrates (especially, polysaccharides), lipids, and nucleic acids. Enzymes that are proteins in nature are polymers of amino acids.Enzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently. Inhibition of enzyme activity is a common mechanism of clinically significant DDIs. Enzyme inhibition decreases the rate of drug metabolism, thereby increasing the amount of drug in the body, leading to accumulation and potential toxicity. Enzyme inhibition may be described by its reversibility, ranging from rapidly reversible to irreversible.Protein, highly complex substance that is present in all living organisms.
