Deficiency of which element affects cytochromes synthesis?

Options

A. Nitrogen
B. Hydrogen
C. Potassium
D. Iron

Answer

**Step-by-Step Solution:**

1. **Understanding Cytochromes**: Cytochromes are proteins that play a crucial role in the electron transport chain, which is a part of cellular respiration. They are involved in the transfer of electrons and are essential for energy production in cells.

2. **Identifying the Structure of Cytochromes**: Cytochromes contain a heme group, which is a complex of iron and a porphyrin ring. The iron atom in the heme group is essential for the redox reactions that occur during electron transport.

3. **Role of Iron in Cytochrome Synthesis**: The iron atom acts as a cofactor in the synthesis of cytochromes. Without iron, the heme group cannot form properly, leading to impaired synthesis of cytochromes.

4. **Consequences of Iron Deficiency**: If there is a deficiency of iron, it will directly affect the synthesis of cytochromes, leading to disruptions in the electron transport chain and, consequently, energy production in the cell.

5. **Conclusion**: Based on the above points, the element whose deficiency affects cytochrome synthesis is iron.

**Final Answer**: The deficiency of iron affects cytochrome synthesis.
