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.
Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life.ollowing Buchner's example, enzymes are usually named according to the reaction they carry out: the suffix-ase is combined with the name of the substrate (e.g., lactase is the enzyme that cleaves lactose) or to the type of reaction (e.g., DNA polymerase forms DNA polymers).
