How enzymes decrease activation energy

WebThe enzyme-substrate complex can also lower activation energy by bending substrate molecules in a way that facilitates bond-breaking, helping to reach the transition state. … Web7 dec. 2024 · Activation energy is the minimum amount of energy required for a chemical reaction to occur. Enzymes and catalysts are important because they help lower the activation energy, making it easier for reactions to take place. One way enzymes lower activation energy is by increasing the rate of the reaction.

Does increasing temperature lower activation energy?
