Answer
Oxygen is not directly used in the glycolysis stage, as this metabolic process occurs anaerobically. Instead, glycolysis breaks down glucose into pyruvate in the cytoplasm.
Step 2
B. to break down ATP molecules to ADP molecules.

Answer
Oxygen does not function to break down ATP into ADP. Instead, ATP is generated during cellular respiration through different processes, including oxidative phosphorylation.
Step 3
C. to combine with carbon dioxide to produce glucose.

Answer
Oxygen does not combine with carbon dioxide to produce glucose; this process, known as photosynthesis, occurs in plants, not during cellular respiration in fish.

Answer
Correct. Oxygen acts as the final acceptor of electrons and hydrogen ions in the electron transport chain, facilitating the production of water and generating ATP effectively.
