What is the reverse of this reaction?

Transcribed Image Text:### Alcohol Metabolism Reaction
This chemical reaction illustrates the conversion of ethanol to acetaldehyde, catalyzed by the enzyme Alcohol Dehydrogenase.
- **Reactants:**
- **Ethanol (C₂H₅OH):** Depicted with the structural formula showing a two-carbon chain with a hydroxyl group (OH) attached to one carbon.
- **NAD⁺ (Nicotinamide Adenine Dinucleotide):** A coenzyme involved in redox reactions, accepting electrons and being reduced in the process.
- **Enzyme:**
- **Alcohol Dehydrogenase:** It facilitates the conversion of ethanol to acetaldehyde.
- **Products:**
- **Acetaldehyde (CH₃CHO):** Shown with a carbonyl group (C=O) attached to one carbon.
- **NADH:** The reduced form of NAD⁺, indicating it has accepted electrons during the reaction.
This reaction is part of the metabolic process where ethanol is broken down in the liver. The production of acetaldehyde is a crucial step but can lead to toxic effects if not further processed by subsequent reactions.
