Biology catalyst definition

WebBTW, positive catalyst is a term for a catalyst that speeds up a reaction. Negative catalysts slow down, or make it harder for a reaction to occur. Please note: This is a very simple explanation for an extremely complex … 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.
