Oxidative phosphorylation involves simultaneous oxidation and phosphorylation to finally form

Options

A. pyruvate
B. NADP
C. DPN
D. ATP

Explanation

**Step-by-Step Solution:**

1. **Understanding Oxidative Phosphorylation**:
- Oxidative phosphorylation is a metabolic process that occurs in the mitochondria of cells. It involves the transfer of electrons through a series of protein complexes (the electron transport chain) and the simultaneous production of ATP.

2. **Identifying the Components**:
- In oxidative phosphorylation, oxidation refers to the loss of electrons from molecules (typically NADH and FADH2), while phosphorylation refers to the addition of a phosphate group to ADP to form ATP.

3. **Role of Oxygen**:
- Oxygen acts as the final electron acceptor in the electron transport chain. When electrons are transferred to oxygen, it combines with protons (H+) to form water.

4. **Formation of ATP**:
- The energy released during the electron transport chain is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. This gradient drives ATP synthesis when protons flow back through ATP synthase (ATPase), leading to the phosphorylation of ADP to form ATP.

5. **Conclusion**:
- The end product of oxidative phosphorylation is ATP. This high-energy molecule is crucial for various cellular activities.

**Final Answer**: The end product of oxidative phosphorylation is ATP (adenosine triphosphate).
