What is the relationship between enzymes and activation energy?

Hello!

Chemical reactions require energy to begin. The reactants must collide with enough energy for bonds to change. This energy is known as activation energy - the difference in energy between that of the reactants and the amount needed for the reaction to occur.

Catalysts lower the activation energy needed for a chemical reaction to occur, therefore also increasing the rate of a reaction. Enzymes are proteins which act as catalysts within cells.

Therefore, enzymes cause the activation energy to lower.

Hope this helps!

nucleus

would be most reasonable answer tbh
