<P> Each pathway generates different waste products . </P> <P> When in the presence of oxygen, cells use aerobic respiration to obtain energy from glucose molecules . </P> <P> Simplified Theoretical Reaction: C H O + 6O → 6CO + 6H O + ~ 30ATP </P> <P> Cells undergoing aerobic respiration produce 6 molecules of carbon dioxide, 6 molecules of water, and up to 30 molecules of ATP (adenosine triphosphate), which is directly used to produce energy, from each molecule of glucose in the presence of surplus oxygen . </P>

Where is the waste product of carbon dioxide being created
