The amount of energy needed fo a reaction to take place is the activation energy. en zymes can lower the activation energy of a chemical reaction, which of the fallowing describes a way that process could happen?

Enzymes lower the activation energy by forming a complex with substrate (enzyme-substrate complex). There are a few mechanisms of enzymes activity:

•Enzymes can change the charge distribution of the molecule

•Enzymes can change the substrate bonds

•Enzymes can reduce the reaction entropy.

All of the mechanisms tend to bring the molecule (reactant) to unstable state called the transition state (high-energy state).
