What is the main function of cellular respiration?
The main purpose is to turn food into usable chemical energy called ATP. Your body can use ATP as a source of energy to function.
Formula: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP (energy)
In foods such as carbohydrates, there is stored chemical energy that the body can't use right away.
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level.
