Answer;
-supporting reactions involving energy transfer
Explanation;
-Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.
-The basic function of an enzyme is to increase the rate of a reaction. Most cellular reactions occur about a million times faster than they would in the absence of an enzyme. Second, most enzymes act specifically with only one reactant to produce products.
