The final electron acceptor in glycolysis is oxygen.

The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Glycolysis**: Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH in the process. It occurs in the cytoplasm of the cell. 2. **Oxygen Requirement**: Glycolysis is an anaerobic process, meaning it does not require oxygen to occur. It can happen in both aerobic (with oxygen) and anaerobic (without oxygen) conditions. 3. **Electron Acceptors in Glycolysis**: During glycolysis, the final electron acceptor is not oxygen. Instead, the electrons are transferred to NAD+ to form NADH. This means that oxygen is not involved in the glycolysis pathway. 4. **Electron Transport Chain**: The final electron acceptor in cellular respiration is oxygen, but this occurs in a different pathway known as the electron transport chain (ETC), which takes place in the mitochondria. Here, oxygen accepts electrons at the end of the chain, leading to the production of water. 5. **Conclusion**: Therefore, the statement "The final electron acceptor in glycolysis is oxygen" is false. The correct information is that the final electron acceptor in glycolysis is NAD+, and oxygen is the final electron acceptor in the electron transport chain. ### Final Answer: The statement is false. The final electron acceptor in glycolysis is not oxygen; it is NAD+. Oxygen is the final electron acceptor in the electron transport chain. ---
