WebEnzymes and activation energy. A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too. WebName one catalyst and draw a sample graph of how a catalyst would affect a reaction. Catalysts work by providing an alternative reaction pathway by lowering the activation energy needed for this new pathway. With lower activation energy, more collisions will have enough energy to overcome the energy barriers. did linus tech tips invent linux
