The flashcards below were created by user andreathors16 on FreezingBlue Flashcards. What would you like to do?


  1. anabolism
    build up
  2. catabolism
    break down
  3. enazymes lower
    activation energy
  4. bacterial catabolism
    include breakdown of glucose to release atp
  5. metabolism produces NADH, FADH, ATP
    • 10 NADH-30ATP
    • 2 FADH-4atp
    • 4 ATP-4 atp

    38 total atp
  6. glycoysis requires
    no oxygen
  7. glucolysis pathway
    • glucose
    • glu-6-p - ADP
    • fruc-6-p
    • fruc-1,6-dip- ADP
    • gly-3-p
    • 3 pga- NADH2
    • 1,3- pga
    • 3 pga- 2atp
    • 2 pga
    • pep
    • pyruvate- 2atp
  8. krebs cycle requires
    oxygen
  9. krebs cycle
    • pyruvate
    • acetyl- coA - NADH2
    • coA+ oxalocetate
    • citrate
    • ketoglutarate- NADH2 -co2
    • succinyl-CoA
    • succinate- FADH2
    • fumarate
    • malate
    • oxalocate- NADH2
  10. anaerobic fermentation
    • pyruvate to
    • lactate, ethanol, co2 propinoate
  11. enzyme temp
    temp increase would destroy cellular protien so must speed up reaction at compatible temps
  12. apoenzyme
    protien part- inactive
  13. holoenzyme
    apoenzyme + cofactor
  14. cofactor
    ions of zinc NAD mag and calcium
  15. conenzyme
    cofacter must be an organic molecule
  16. enzyme mechanism
    • substrate + active site= enzyme substrate complex
    • subtrate transformed into products then released
    • enzyme unchanged
  17. ph for enyme best at
    5ph
  18. non competitive inhibitors bind at
    • allosteric sight so the activation site changes shape - nonfunctional
    • activity then reduced
  19. competitve inhibitors
    bind in the active site so substrate cannot
  20. ATP
    • high energy bonds
    • energy currency
    • unstopable bonds
  21. oxidation
    loss electrons
  22. reduction
    gain electrons
  23. substrate phos
    atp generated fro direct transer
  24. glucose most comnon
    carb energy source used by a cell
  25. respiration
    • glucoylisis
    • krebs cycle
  26. fermentation
    • glycolusis
    • lactic acid
    • alchol
    • co2
  27. anaerobic respiration
    final electron acceptor is inorganic molecule
  28. aeorbic respiration
    final electron acceptor is 02
