WebHow do enzymes affect the activation energy? Enzymes lower the activation energy that is needed, making reactions happen at a lower temperature that they could without the enzyme. This speeds up the rate of reaction. What is a catalyst? A substance which speed up a chemical reaction without being used up in the reaction itself. 1. WebMar 2, 2024 · By. Theresa Phillips. Updated on March 02, 2024. An enzymes is a protein that facilitates a cellular metabolic process by lowering activation energy (Ea) levels in order to catalyze the chemical reactions between biomolecules. Some enzymes reduce the activation energy to such low levels that they actually reverse cellular reactions.
