Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product. Therefore, the synthesis ...

If these enzymes are not present or functional then the reactions will not occur, so the breakdown of glucose is controlled ... produce a greater quantity of ATP. A pyruvate molecule enters ...

The whole pathway is pure chemistry, involving the reaction of one molecule with ... to transfer the energy from the oxidation of glucose to form ATP) was doomed to failure. In place of such ...
