Study Notes
Enzymes Overview
- Enzymes are biological catalysts that accelerate chemical reactions in living organisms.
- Composed primarily of proteins, they lower the activation energy required for reactions to occur.
Steps of Enzyme-Catalyzed Reactions
- Substrate Binding: The substrate (reactant) binds to the enzyme at the active site.
- Formation of Enzyme-Substrate Complex: This binding forms a temporary complex, allowing the reaction to proceed.
- Product Formation: The enzyme catalyzes the conversion of substrate into product.
- Release of Product: The product is released, and the enzyme is free to catalyze another reaction.
Components of Conjugated Protein Enzymes
- Apoenzyme: The protein component that requires activation.
- Cofactor: A non-protein component which can be a metal ion or a coenzyme that assists in the enzyme's catalytic activity.
Enzymes for Oxidation-Reduction Reactions
- Oxidoreductases are the class of enzymes that catalyze oxidation-reduction reactions, facilitating the transfer of electrons between molecules.
Function of the Catalytic (Active) Site
- The active site is a specific region on the enzyme where substrate binding occurs.
- It is crucial for determining the enzyme's specificity and facilitating the conversion of substrates into products through precise interactions.
