Options

A. A-ii,B-iii,C-iv,D-i
B. A-iii,B-iv,C-ii,D-i
C. A-ii,B-I,C-iii,D-iv
D. A-iv,B-iii,C-I,D-ii

Answer

To solve the matching question, we will analyze each item in Column A and find its corresponding match in Column B step by step.

### Step-by-Step Solution

1. **Molecular Oxygen**:
- Molecular oxygen (O₂) is known to act as an electron acceptor in cellular respiration. It combines with electrons and protons to form water.
- **Match**: Molecular oxygen → Hydrogen acceptor (ii).

2. **Electron Acceptor**:
- In the context of cellular respiration, cytochrome c is a well-known electron acceptor that plays a crucial role in the electron transport chain.
- **Match**: Electron acceptor → Cytochrome c (iii).

3. **Pyruvate Dehydrogenase**:
- Pyruvate dehydrogenase is an enzyme that catalyzes the conversion of pyruvate into acetyl coenzyme A during the link reaction of cellular respiration.
- **Match**: Pyruvate dehydrogenase → Acetyl CoA (iv).

4. **Decarboxylation**:
- Decarboxylation is a chemical reaction that involves the removal of a carboxyl group, and it occurs in the Krebs cycle, specifically with alpha-ketoglutaric acid.
- **Match**: Decarboxylation → Alpha-ketoglutaric acid (i).

### Final Matches
- A: Molecular oxygen → ii: Hydrogen acceptor
- B: Electron acceptor → iii: Cytochrome c
- C: Pyruvate dehydrogenase → iv: Acetyl CoA
- D: Decarboxylation → i: Alpha-ketoglutaric acid

### Correct Option
Based on the matches, the correct option is:
- A → ii
- B → iii
- C → iv
- D → i
