Study Notes
Enzyme Kinetics
- The active site of an enzyme primarily binds to substrate molecules.
Enzyme Complex
- The complete enzyme complex is known as the holoenzyme, which consists of the enzyme (apoenzyme) and its cofactor.
Km of Enzyme
- Km (Michaelis constant) of an enzyme represents the substrate concentration at which the reaction rate is half of the maximum velocity (Vmax).
Enzyme-Catalyzed Reaction
- The velocity (V) of an enzyme-catalyzed reaction relates to the rate at which the enzyme converts substrate into product.
Competitive Inhibition
- A competitive inhibitor of an enzyme binds to the active site, reducing the binding of substrate and decreasing the reaction rate.
