The flashcards below were created by user see.jerald on FreezingBlue Flashcards. What would you like to do?


  1. How many stages are in Cellular respiration?
    3
  2. In prokaryotic cells that use aerobic respiration, where do the steps occur?
    in the cytoplasm
  3. In prokaryotic cells, where is the electron transport chain embedded in?
    the plasma membrane
  4. What is stage 2 of cellular respiration?
    the citric acid cycle
  5. Where does the citric acid cycle take place?
    mitochondria
  6. how does the citric acid cycle complete the break down of glucose?
    by decomposing a derivative of pyruvate to carbon dioxide
  7. During the first 2 stages of CR is there a lot of ATP made?
    no
  8. What is the main function of glycolysis and the citric acid cycle?
    to supply the 3rd stage (oxidative phosphorylation) with electrons
  9. What process does oxidative phosphorylation include?
    the ETC and chemiosmosis
  10. What shuttles electrons into the ETC?
    NADH and FADH
  11. Where does NADH and FADH get shuttled into
    the inner mitochondrion membrane
  12. During what stage is most ATP made?
    oxidative phosphorylation
  13. How do cells generate ATP?
    through adding a phosphate to ADP
  14. What couples the electron transport chain to ATP synthesis?
    as the ETC transports electrons down the staircase, it also pumps hydrogen ions across the mitochondrial membrane
  15. Where does H+ go after the inner mitochondrial membrane?
    narrow intermembrane space
  16. In chemiosmosis, which concentration gradient creates the potential energy which pumps the H+?
    the ETC pumping H+ ions into the inner mitochondrial membrane into the narrow intermembrane space
  17. What is ATP synthase?
    protein complexes built into the inner membrane that synthesis ATP
