Write the formula that shows the release of energy by the mitochondria
Pie

Answer:

Mitochondria is the organelle where cellular respiration takes place. Cellular respiration can be described as a process in which oxygen and glucose are converted into carbon dioxide and water along with the release of ATP. This reaction can be written as:

Glucose + Oxygen → Carbon dioxide + Water + ATP molecules

C6H12O6 +   6O2→  6CO2 +  6H2O +  ATP

The ATP made can be broken down so that energy is released.

ATP + H2O → ADP + Pi + free energy
