Explanation:

Enzyme is a protein that speeds up the rate of a chemical reaction without being permanently changed. Enzymes are biological catalysts that catalyze biochemical reactions and remain unchanged after the reaction.The shape of the enzyme provides a pocket called the active site,which allows the substrate to temporarily attach.Substrate is the molecule that is acted on by the enzyme. Enzyme are substrate specific, therefore an enzyme will act on a specific substrate that can fit on its active site.The product is the result of the enzyme catalysis. After catalysis the substrate is converted to a product and the enzyme remains unchanged.
