Question

Observe the chemical reaction and identify the enzyme and its prosthetic group:

Hint:

Associate enzyme with its prosthetic group and reaction:
Catalase → H2O2 decomposition, Haem group.
Hexokinase → glucose phosphorylation, Mg2+.
Urease → urea hydrolysis, Zn2+.

Answer 1

1. Catalase catalyzes decomposition of H2O2 into H2O and O2.
2. Catalase requires Haem as prosthetic group for redox reaction.
3. Peroxidase, Hexokinase, Urease act on different substrates.
4. Hence correct answer is (2) Catalase, Haem.
