Cellular respiration

• Aerobic cellular respiration equation

  A) glucose

  B) oxygen

  C) carbon dioxide

  D) water

  E) atp

  
• Aerobic respiration:

  1. Glycolysis - using NAD+ and FAD, glucose molecules are broken down into pyruvic acid in the cytosol (liquid of cells), producing 2 ATP
  2. Krebs Cycle - 8 cyclic reactions, where pyruvic acid diffuses into mitrochondrial matrix through cytoplasm, and energy transferred to coenzymes, producing 2 ATP
  3. Electron Transfer Chain - Occuring in the cristae of the mitochondria, protons and oxygen move across cell membrane, producing 26-28 ATP, oxygen picks up electrons at the end of the chain
• Anaerobic respiration:

  • Glycolysis (cytosol)
  • Fermentation (cytosol) - lactic acid (animals) or ethanol (plants) is produced
