What is the role of haem in peroxidase and catalase?
What is the role of haem in peroxidase and catalase?
Options
- ATo make the enzyme catalytically active.
- BTo tightly bind to the apoenzyme.
- CTo catalyze the breakdown of hydrogen peroxide.
- DTo be a part of the active site of the enzyme.
Correct answer
D. To be a part of the active site of the enzyme.
Step-by-step solution
Prosthetic groups are organic compounds and are distinguished from other cofactors in that they are tightly bound to the apoenzyme. For example, in peroxidase and catalase, which catalyze the breakdown of hydrogen peroxide to water and oxygen, haem is the prosthetic group and it is a part of the active site of the enzyme.
