WebbA simple and succinct definition of an enzyme is that it is a biological catalyst that accelerates a chemical reaction without altering its equilibrium. During the reactions the enzymes themselves undergo transient changes. In the overall process, enzymes do not undergo any net change. WebbEnzymes are biological catalysts. Just like other catalysts, they reduce activation energy, allowing reactions to proceed in a desired direction. Because their activity is dependent on the folding of a protein, they are usually sensitive to the temperature, pH, and salt concentration of the environment they work in.
