An enzyme is simply a protein (a folded chain of amino acids, which are the building blocks of proteins). Generally, they're extremely long and folded chains, often in excess of 500 amino acids! These chains generally fold themselves because of chemical/magnetic forces between the amino acids. Sort of like a wire coil or accordion... if you let go of it, it springs back to an original position.
Mechanisms of Enzyme action. Enzymes are essential proteins that are found in all living cells. They have two main functions: 1) they act as catalysts ( a catalyst is a chemical which speeds up a chemical reaction ) 2) they control all the chemical reactions going on inside the cell. Every cell has many different enzymes. Each enzyme is specific : it only affects one particular chemical.
