  • In cellular respiration, energy stored in a glucose molecule is released through a series of reactions occurring in two stages: glycolysis and the citric acid cycle (or Krebs cycle) with an intermediate step that converts the pyruvate produced in glycolysis into the acetyl-CoA needed for the Kreb's cycle. Cells can often use other molecules such as amino acids, and fatty acids as an energy source by breaking down the molecules into substances that enter cellular respiration at their corresponding point in the pathway.
