Which one is component of ferredoxin ?

Options

A. Zn
B. Mn
C. Cu
D. Fe

Answer

**Step-by-Step Solution:**

1. **Understanding Ferredoxin**: Ferredoxins are small proteins that play a crucial role in various biological processes, particularly in electron transfer reactions.

2. **Identifying Components**: The key components of ferredoxins are iron (Fe) and sulfur (S) atoms. These elements are essential for the structure and function of ferredoxins.

3. **Structure of Ferredoxin**: In ferredoxins, iron and sulfur atoms are organized into clusters known as iron-sulfur clusters. This organization is vital for their electron transfer capabilities.

4. **Function of Ferredoxin**: Ferredoxins act as biological capacitors, which means they can accept and discharge electrons. This property is important for various biochemical reactions.

5. **Choosing the Correct Option**: Given the options (a. Zinc, b. Manganese, c. Copper, d. Iron), the correct answer is option d, Iron (Fe), as it is a key component of ferredoxin.

**Final Answer**: The component of ferredoxin is Iron (Fe).
