Storyboard Text

  • Cellular Respiration
  • Cellular respiration (C6H12O6 + 6O2 → 6CO2 + 6 H2O + energy (ATP + heat)), mostly occurs within the mitochondria and has three stages.
  • Mitochondria
  • Glycolysis is a process in cellular respiration that occurs in the cytoplasm outside of the mitochondria.
  • Cytoplasm
  • The starting material for glycolysis, glucose, is broken down and separated to form 2 pyruvates, net 2 ATP + 2 NADH.
  • The next two processes, Krebs cycle and Electron transport chain, will only occur if oxygen is present, and if so, will take place within the mitochondria.
  • The Krebs cycle takes place within the mitochondrial matrix. It’s products include 6 carbon dioxide molecules, 8 NADH, 2 FADH2, and 2 ATP.
  • MitochondrialMatrix
  • Inner Membrane
  • Finally, the ETC (Electron Transport Chain) will combine oxygen molecules and hydrogen molecules (hydrogen from the 8 NADH and FADH2) to create water and over 30 ATP. This process occurs in the inner membrane of the mitochondria.
