Which one of the following enzymes contains 'Haem' as the prosthetic group?

A RuBisCo
B Carbonic anhydrase
C Succinate dehydrogenase
D Catalase

Verified Solution

Answer & Solution

Correct Answer

(D) Catalase

Step-by-step Solution

Detailed explanation

In peroxidase and catalase, which catalyze the breakdown of hydrogen peroxide to water and oxygen, haem is the prosthetic group and it is part of the active site of the enzymes.
Zinc is the cofactor in enzyme carbonic anhydrase.
RuBisCo is the most abundant protein in whole of the biosphere.
Succinate is the substrate of enzyme succinic dehydrogenase.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
