The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products.ome household products use enzymes to speed up chemical reactions: enzymes in biological washing powders break down protein, starch or fat stains on clothes, and enzymes in meat tenderizer break down proteins into smaller molecules, making the meat easier to chew.
