There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation.
Glycolysis is the initial step in cellular respiration, and in some simple cells, the only one. Glycolysis is the cleavage of glucose, a six-carbon sugar, into two three-carbon pyruvic acid molecules. Getting the process going requires the energy stored in two molecules of ATP.
