Here's why:
* Glucose is the fuel: Cellular respiration uses glucose as its primary energy source.
* Oxygen is the oxidizer: Oxygen acts as the electron acceptor in the process, allowing the breakdown of glucose to release energy.
* Carbon dioxide is a byproduct: Carbon dioxide is produced as a waste product during cellular respiration.
Here's a simplified summary of cellular respiration:
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
