What is the difference between an enzyme and a catalyst?
Posted January 29, 2021
Answer
Both, enzymes and catalysts affect the rate of a reaction without being consumed in the reactions themselves. All known enzymes are catalysts, but not all catalysts are enzymes.
Enzyme
- Is an organic biocatalyst
- Is a high molecular globular protein
- All known enzymes are catalysts
- Enzyme reaction rates are faster
- Increases the rate of chemical reactions and converts the substrate into a product
- Highly specific, producing large amounts of good residues
- C-C and C-H bonds are present
- Two types include activation and inhibitory enzymes
- Examples include lipase and amylase
Catalyst
- Is inorganic
- Is a low molecular weight compound
- All catalysts are not enzymes
- Catalyst reaction rates are typically slower
- May increase or decrease the rate of a chemical reaction
- C-C and C-H bonds are absent
- Not specific and may produce residues with errors
- Two types include positive and negative catalysts
- Example includes vanadium oxide
