Enzyme Catalysis
Easychemistry
Enzyme catalysis is an example of:
Select the correct option:
Solution
Incorrect! Answer:
Homogeneous catalysis
Homogeneous Catalysis occurs when the catalyst and the reactants are in the same physical phase.
- In biological systems, Enzymes (high molecular weight proteins) and their substrates are both typically dissolved in the aqueous cytoplasm or blood.
- Since they are in the same liquid phase, enzyme catalysis is a classic example of homogeneous catalysis.
- Note: Some consider it 'micro-heterogeneous' because enzymes have distinct active sites, but for JEE level, it is generally treated as homogeneous in the context of phase.
