They are essential for life, as they allow cells to function properly.<\/p>\n<p>Hormones are chemical messengers that are produced by glands in the body and transported to other parts of the body, where they regulate physiological processes. Vitamins are essential nutrients that the body needs in small amounts to function properly. They are not produced by the body, so they must be obtained from food.<\/p>\n<p>Here is a brief description of each type of enzyme:<\/p>\n<ul>\n<li>Oxyreductases: catalyze oxidation-reduction reactions.<\/li>\n<li>Transferases: catalyze the transfer of a chemical group from one molecule to another.<\/li>\n<li>Hydrolases: catalyze the hydrolysis of (breakdown of) molecules by the addition of water.<\/li>\n<li>Lyases: catalyze the cleavage of molecules without the addition of water.<\/li>\n<li>Isomerases: catalyze the isomerization of molecules (the conversion of one isomer to another).<\/li>\n<li>Ligases: catalyze the joining of two molecules together.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on
