Prosthetic groups differ from coenzymes in that
Options
- Athey require metal ions for their activity
- Bthey (prosthetic groups) are tightly bound to apoenzymes
- Ctheir association with apoenzymes is transient
- Dthey can serve as cofactors in a number of enzyme catalysed reactions
Correct answer
B. they (prosthetic groups) are tightly bound to apoenzymes
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 catalyse 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.
