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

Options

  1. ARuBisCo
  2. BCarbonic anhydrase
  3. CSuccinate dehydrogenase
  4. DCatalase

Correct answer

D. Catalase

Step-by-step solution

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.
