Answer
The three parts of cellular respiration are glycosis, the citric acid cycle, and the electron transport chain.
During glycosis a molecule of glucose is split into two three carbon molecules of pyruvate. NADH is the result of glycosis, and those bonds are broken down to yield two molecules of ATP.
The citric acid cycle continues to break up the remaining carbon-carbon bonds and releases carbon dioxide and a small amount of ATP as a result.
NADH molecules from glycolysis and the citric acid cycle deliver electrons to the electron transport chain. As high energy electrons are passed from carrier to carrier they lose energy. Oxygen accepts these electrons at the end of the chain. The oxygen then combines with hydrogen to create water.
