Enzymes increase reaction rate by
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 … WebEnzymes act as catalysts to speed up chemical reactions by raising the activation energy required for the reaction. Each enzyme binds to a specific substrate at the active site. Coenzymes and cofactors are enzyme activators that increase reaction rates. Enzyme activity may be affected by temperature, substrate This problem has been solved!
