In living cells, WHAT serve as biological catalysts. Each acts on a specific substance called the enzyme's substrate and each catalyzes only one reaction. As catalysts, enzymes typically accelerate chemical reactions. The enzyme molecule has an active site, a region that will interact with a specific chemical substance.
What does an enzyme do? Enzymes are biological proteins that are used to catalyze chemicalreactions on organic molecules. The substrates (reactant molecules)bind to the enzyme, and the energy to combâ¦ine it with anothermolecule or break it down is reduced in the process, inducing thechemical change to another product.
