How do enzymes alter activation energy

WebEnzymes function to reduce the activation energy required for a chemical reaction to occur. First, the enzyme binds to the substrate and slightly distorts its shape. The change in shape activates the substrate molecule and decreases the total activation energy required for the substrate to be turned into product. WebActivation Energy – energy needed to start a reaction between two or more elements or compounds Catalyst – A molecule that increases the rate of reaction and not consumed in the reaction Turnover Number – the number of reactions one enzyme can catalyze per second Enzyme – a biological catalyst made of amino acids.
