Question

Hema-protein complex acting as oxidising agent is

• A. Haemoglobin
• B. Myoglobin
• C. Chlorophyll
• D. Cytochrome

Answer 1

The correct option is D Cytochrome

Cytochromes are iron containing protein. It helps in the generation of ATP by electron transport chain. It helps in the transfer of electrons by oxidation and reduction. In haema-protein the iron present in the the cytochrome gets converted from Fe${}^{2+}$ into Fe${}^{3+}$ . It also transfers electrons between complex III and complex IV during electron transport chain so it acts as a oxidising agent.

So, the correct answer is option D.
