Why does cellular respiration add carbon dioxide to the atmosphere but photosynthesis does not? During photosynthesis, carbon dioxide and water are used to produce sugars and oxygen. During respiration, the sugar glucose and oxygen and used to produce carbon dioxide and â¦water.  Resource: Science Explorer. Prentice Hall Life Science Text Book. No copyright intended.
As a result, there is a net gain of two ATP molecules during glycolysis. During this stage, high-energy electrons are also transferred to molecules of NAD + to produce two molecules of NADH, another energy-carrying molecule. NADH is used in stage III of cellular respiration to make more ATP.Here is a summary of glycolysis:nergy is needed at the start of glycolysis to split the glucose molecule into two pyruvate molecules. These two molecules go on to stage II of cellular respiration. The energy to split glucose is provided by two molecules of ATP.
