Here's a breakdown:

* Reactants: Glucose (C6H12O6) and oxygen (O2)

* Products: Carbon dioxide (CO2), water (H2O), and energy (ATP)

Cellular respiration is a series of metabolic reactions that occur in the cells of organisms to convert chemical energy from glucose into a form usable by the cell (ATP). It can be summarized by the following equation:

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP)

This process is crucial for life, as it provides the energy required for all cellular functions, including growth, movement, and repair.
