Hormones vs. Enzymes: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Hormones are chemical messengers regulating bodily functions, while enzymes are proteins that catalyze biochemical reactions.
Key Differences
Hormones are signaling molecules produced by glands, traveling through the bloodstream to tissues and organs. Enzymes, in contrast, are biological catalysts accelerating chemical reactions in cells.
