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.
Enzymes are catalysts which speed up reactions, they are made from protein and are specific as to which substrate they work on. Enzymes basically work due to the lock and key theory, where the substrate substance (the key) fits into the active site on the enzyme and they bind together, the reaction takes place and the substrate unlocks to
