Mineral element present in cytochrome is

Options

A. potassium
B. Zinc
C. Iron
D. Manganese.

Answer

**Step-by-Step Solution:**

1. **Understanding Cytochromes**: Cytochromes are proteins that play a crucial role in the electron transport chain, which is essential for ATP generation in cellular respiration.

2. **Identifying the Mineral Element**: The question asks for the mineral element present in cytochromes. Cytochromes are specifically known to contain a metal ion that is integral to their function.

3. **Analyzing the Options**: The options provided are:
- Potassium
- Zinc
- Iron
- Manganese

4. **Recognizing the Role of Iron**: Cytochromes are classified as heme-containing proteins, which means they have a heme group that includes iron. This iron is crucial for the electron transfer process.

5. **Conclusion**: Since cytochromes are iron-containing proteins, the correct answer to the question is **Iron**.
