Which one of the following statements about cytochrome `P_(450)` is wrong

Options

A. It contains iron
B. It is a coloured cell
C. It has an important role in metabolism
D. It is an enzyme involved in oxidation reactions

Explanation

### Step-by-Step Solution:

1. **Understanding Cytochrome P450**:
- Cytochrome P450, also known as CYP, is a family of enzymes that play a crucial role in the metabolism of various substances in the body. They are involved in the oxidation of organic substances.

2. **Function of Cytochrome P450**:
- These enzymes utilize iron to oxidize harmful components, making them more soluble. This increased solubility facilitates the excretion of these substances from the body.

3. **Presence in Organisms**:
- Cytochrome P450 enzymes are found in a wide range of organisms, including plants, animals, and certain microbes.

4. **Types of Reactions Catalyzed**:
- Cytochrome P450 enzymes catalyze various oxidative reactions, including hydroxylation, oxidation, and alkylation.

5. **Typical Reaction Mechanism**:
- A typical reaction involving cytochrome P450 can be summarized as:
- NADPH + H⁺ + O₂ → NADP⁺ + H₂O + Alcohol (from alkyl compounds).

6. **Evaluating Statements**:
- When evaluating statements about cytochrome P450, we find that:
- It contains iron (True).
- It plays an important role in metabolism (True).
- It is involved in oxidative mechanisms (True).
- The statement that it is a "coloured cell" is incorrect.

7. **Conclusion**:
- The wrong statement about cytochrome P450 is that it is a "coloured cell." Therefore, the correct answer to the question is that this statement is false.

### Final Answer:
The wrong statement about cytochrome P450 is that it is a "coloured cell."
