Enzyme required to oxidised acetaldehyde is

Options

A. Ethanol oxidase
B. Acetaldehyde dehydrogenase
C. Alcohol hydrogenase
D. Glyceraldehyde dehydrogenase

Answer

To answer the question regarding the enzyme required to oxidize acetaldehyde, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Context**: Acetaldehyde is a product formed during the metabolism of alcohol in the body. When alcohol is consumed, it undergoes a series of metabolic reactions.

2. **Initial Breakdown of Alcohol**: The first step in alcohol metabolism involves the enzyme **alcohol dehydrogenase**, which converts alcohol (ethanol) into acetaldehyde.

3. **Oxidation of Acetaldehyde**: The question specifically asks for the enzyme that oxidizes acetaldehyde. After acetaldehyde is formed, it needs to be further metabolized because it is toxic.

4. **Identifying the Correct Enzyme**: The enzyme responsible for the oxidation of acetaldehyde into acetate is **acetaldehyde dehydrogenase**. This enzyme catalyzes the reaction that converts acetaldehyde into acetate, which is less toxic.

5. **Conclusion**: Therefore, the enzyme required to oxidize acetaldehyde is **acetaldehyde dehydrogenase**.

### Final Answer:
The enzyme required to oxidize acetaldehyde is **acetaldehyde dehydrogenase**.
