[DIAGRAM: A chemical reaction showing the breakdown of hydrogen peroxide into water and oxygen: H2O2 → H2O + O2.] In the enzyme which catalyses the breakdown of H2O2 → H2O + O2, the prosthetic group is:

  1. (A)Niacin
  2. (B)Nicotinamide adenine dinucleotide
  3. (C)Haem
  4. (D)Zinc

The NCERT line that answers it

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states that in catalase (which catalyzes H2O2 breakdown), haem is the prosthetic group, directly matching the question and correct answer.
