Enzymes are proteins that act as catalysts

WebEnzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently. WebJun 6, 2024 · Enzymes ARE in fact biological catalysts.
