Study Notes
Enzymes in Biological Reactions
- Enzymes are biological molecules that catalyze chemical reactions, increasing their rates and efficiency.
Structure of Enzymes
- A holoenzyme is a complete enzyme consisting of a protein component (apoenzyme) and a cofactor.
- The specific region of an enzyme where the substrate binds and catalysis occurs is called the active site.
Enzyme Function
- Enzymes lower the energy barrier required for a reaction to occur, allowing the reaction to proceed more quickly and efficiently.
Cofactors
- Small organic molecules that function as cofactors are called coenzymes.
- Cofactors that are tightly bound to the enzyme are called prosthetic groups.
