Final answer:
The number of ATP molecules formed through cellular respiration varies due to multiple factors including oxygen availability, glucose concentration, and temperature.c) Temperature affects ATP production
Step-by-step explanation:
The number of ATP molecules formed through cellular respiration varies due to multiple factors. The claim that accounts for these differences is d) All of the above. Oxygen availability affects ATP production because it is the final electron acceptor in the electron transport chain. Glucose concentration affects ATP production because it is the substrate that is broken down during cellular respiration. Temperature affects ATP production because enzymes involved in the process are temperature-sensitive.
