Difference Between Active Site and Binding Site

WebThe active site of an enzyme also creates an ideal environment, such as a slightly acidic or non-polar environment, for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. WebOct 18, 2008 · Copy. An enzyme is a biological catalyst.
