Enzymes

 

Enzymes are proteins that control the rate of reaction

            They lower activation energy

 

Characteristics of enzyme-controlled chemical reactions

            The enzyme is unchanged after the reaction

            Enzymes have high specificity

            The active site of the enzyme binds to the substrate

            Enzymes often are aided by coenzymes

 

Enzyme competition in cells is affected by:

            temperature

            pH

            relative numbers of enzyme molecules

            enzyme inhibitor molecules
