How are enzymes different from 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. WebENZYMES Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. There are approximately 1300 different enzymes found in the human body. …
