Formula for aerobic respiration is as follows:Glucose + Oxygen = Carbon Dioxide + Water + ATP (or in GCSE 'energy')C6H12O6 + 6O2 = 6CO2 + 6H2O + 36 ATP (can vary between 34-38 ATP)Only 30-40% is converted into ATP, the rest is given off as heat.ATP stands for adenosine triphosphate. It is used to store energy in your muscles. When one of the phosphate molecules in ATP is broken off it becomes adenosine diphosphate or ADP. As the bond is broken, energy is released and we use this energy in our body for different functions. It can be converted back into ATP. energyCO2, H2O and ATP
