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.
How Enzymes work. 1. Enzymes catalyse only those reactions that happen naturally. 2. Enzymes are specific: each enzyme is responsible for only 1 kind of reaction, because they are shaped to work with only a certain substrate that matches enzyme's active site. 3. Enzyme changes its conformation when substrate bonds to its active site.
