BioChem Cellular Respiration Quiz 3

  1. Where does glycolyis occur in a cell?
  2. How many carbons is one mole of glucose comprised of?
  3. What are the two phases of Glycolysis?
    • Preparatory / Investment phase
    • Pay-off-Phase
  4. Where does Pyruvate dehydrogenase complex occur?
    Inner Mitochondria
  5. How many ATP equivalents are released by each pyruvate during Pyruvate dehydrogenase complex?
    • 1 NADH = 3 ATP equi
    • Total Per Glucose = 2 NADH = 6 ATP equi
  6. What is Pyruvate converted to during Pyruvate Dehydrogenase Complex?
  7. What are the irreversable steps of glycolysis?
    • 1 Hexokinase
    • 3 Phosphofructokinase
    • 10 Pyruvate Kinase
  8. How is Hexokinase regulated?
    • Product inhibition (neg-heterotropic)
    • i.e. inhibited by saturation of glucose-6-phosphate
  9. How is Phosphofructokinase regulated?
    • Inhibited by ATP and Citrate
    • Activated by ADP, AMP, fructose 2,6 bisphosphate
  10. How is Pyruvate Kinase regulated?
    • Inhibited by high ATP concentration
    • Activated by fructose 1,6 bisphosphate
  11. What type of cellular respiration is the Cori Cycle?
  12. Where does the Cori cycle occur?
    muscle to liver
  13. What are the three names for the Kreb Cycle?
    • Kreb Cycle
    • Tricarboxylic Acid Cycle (TCA)
    • Citric Acid Cycle
  14. What must occur between Glycolysis and TCA?
    • Pyruvate Dehydrogenase Complex
    • Pyruvate to Acetly-CoA
  15. How many ATP equ per pyruvate in TCA cycle?
    12 ATP Equ
  16. How many ATP Equ per mole Glucose in Citric Acid Cycle?
  17. Where does the Kreb Cycle Occur in the cell?
    In the Mitochondria
