Q2 / 180 · NEET 2025 · Biology

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

  • A
    RuBisCo
  • B
    Carbonic anhydrase
  • C
    Succinate dehydrogenase
  • Correct answer
    D
    Catalase

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.

Hence, the correct answer is option: 'D'.
