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 large molecules that speed up the chemical reactions inside cells. Each type of enzyme does on specific job. Enzymes are a type of protein, and like all proteins, they are made from long chains of different amino acids. Biological catalysts Enzymes are soluble protein molecules that can speed up chemical reactions in cells. These reactions include respiration, photosynthesis and making new proteins. For this reason enzymes are sometimes called biological catalysts. Enzymes speed up (catalyse) chemical reactions occurring inside and outside of living cells.
