  1. ATP?
    Stands for adenosine triphosphate

    these are energy carrier molecules
  2. Glycolysis
    Begins the breakdown of glucose(6-carbon sugar) producing 2 pyruvates(3-carbon sugar)

    Also makes two ATP molecules
  3. Aerobic
    with oxygen
  4. Anaerobic
    without oxygen
  5. Cellular Respiration
    the two pyruvate, produced from glycolysis, are broken down into 6 CO2 molecules and 6 H2O molecules
  6. When is Oxygen used in Cellular Respiration?
    the last stage which produces an additional 34-36 ATP molecules for every 2 pyruvate molecules that enter the cycle.
  7. Where does Cellular Respiration occur in Eukaryotic cell?
    Mitochondria which are specialized for aerobic breakdown of pyruvate.
  8. If oxygen is not available, the second stage of the glucose breakdown is____
  9. Fermintation
    pyruvate does not enter mitochondria like in cellular respiration

    it instead remains in cytoplasm and is converted into either lactace, or into ethanol and CO2
  10. ADP
    Stands for Adenosine diphosphate

    it is made from a energy-depleted ATP because it has one less Phosphate group
  11. NAD / NADH
    • NAD- nicotinamide adenine dinucleotide
    • NADH- its NAD plus one H ion

    these are high-energy electron-carriers
  12. Citric Acid Cycle
    also called Krebs Cycle

    With 2 acetal CoA molecules, it will produce: 6 NADH, 2 FADH2, 2 ATP
