  • Glycolysis is the first step in Cellular Respiration and it begins with glucose.
  • Mitrochondia generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
  • After glycolysis, pyruvic acid is produced which is used in the Krebs cycle.
  • So now in the mitochondria.
  • Still in mitochondria
  • The Krebs Cycle also completes the breakdown of glucose to carbon dioxide.
  • Futher redox in the Kreb Cycle reduce the electron carriers NAD+ and FAD to FADH2 and NAHD.
  • Still in mitochondria
  • NAHD and FAHD molecules go through the Electron Transport Chain to oxygen, the final electron receptor.
  • Still in mitochondria
  • Chemiosmosis uses energy stored in hydrogen ion gradient across a membrane to drive ATP synthesis. The OXYGEN they will start producing up to 32 ATP
  • A rush of H+ activate catalystic sites that attach phosphate groups to ADP to generate ATP.
  • The fianally product of Cellular Respiration is 32 ATP + H2O + CO2
