Question

..................... enzymes have heme as a prosthetic group.
(i) Catalase
(ii) Carboxypeptidase
(iii) Succinic dehydrogenase
(iv) Peroxidase

• A. (i) only
• B. (i) and (ii) only
• C. (ii) and (iii) only
• D. (iii) and (iv) only
• E. (i) and (iv) only

Answer 1

The correct option is E (i) and (iv) only

Some enzymes, for catalytic function, in addition to the apoprotein part require a tightly covalently linked non protein part called as prosthetic group. Heme is a iron containing prosthetic group used by enzymes like catalase and peroxidase.
