Final answer:
Cellular respiration is the process by which energy from food molecules is captured by an organism. It involves the conversion of glucose and oxygen into carbon dioxide, water, and ATP.
Step-by-step explanation:
Cellular respiration is the process by which energy from the chemical bonds of food molecules is captured by an organism. It involves a series of chemical reactions that convert glucose and oxygen into carbon dioxide, water, and ATP (adenosine triphosphate), which is the molecule that provides energy for the cell. The overall equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.
