Hormones and enzymes are distinct biological substances with different functions: hormones are chemical messengers released by endocrine glands to regulate various bodily processes by traveling through the bloodstream, while enzymes are protein catalysts produced by glands to speed up specific chemical reactions, often working at their site of production or within a duct system. The term “endocrine enzymes” is a misnomer; enzymes are catalysts, and hormones are chemical messengers, although some endocrine glands, like the pancreas, also produce exocrine enzymes for digestion in addition to endocrine hormones like insulin and glucagon.
