    Kreb Cycle

    to make Energy Taxi

    (NADH+FADH2) ?? ask Larry
  13. Hoe much ATP is made during the Kreb Cycle?
  14. Good thing and Bad thing about aerobic respiration
    • Good ting - makes a lot of ATP
    • Bad thing - slow and needs O2
  15. What is the importance of Oxygen
    • it acts as the terminal electron acceptor
    • and allows full breakdown
  16. what does the Proton Pump do?
    Builds the Gradient
  17. what does the gradient do?
    (the one that the  proton pump makes)
    powers the ATP Synthase

  19. How many ATP are made throughout the Aerobic
    about 28

    or 32

    ask larry
  20. where does the Electron Transport take place
    in the cristae of the mitochondria (inner lining)
  21. what happens during oxidative phosphorylation (Electron Transport)
    • electrons from NADH and FADH2 are transported along an electron transport chain
    • As electrons are passed through the electron transport chain, H+ is pumped out of the matrix into the inner membrane
    • the flow of H+ makes ADP produce ATP
    • electron then bind with oxygen to form water

    the liver

    adipose tissue
  24. lactic acid and amino acid come from
  25. How do cell communicate with each other?
    by secreting chemical regulators into the extrcellular environment
  26. Describe body fluid break down
    __ of our water is within cells __ in extracellular
    67% in within the cells in the intracellular compartment

    • 33% is in the extracellular compartment
    • of that 33% ---20% is in the blood and 80% makes up interstitial fluid; connects the intracellular compartment with the blood plasma
  27. Passive Transport
    molecules move from higher to lower concentration without using metabolic energy
  28. Active Transport
    Molecules move from lower to higher concentrations using ATP and specific carrier pumps
  29. a solution consists of
    • a solvent (water)
    • solute (molecules dissolved in water)
  30. where are sodium potassium pumps found
    in all body cells
  31. what are the 3 functions of the sodium potassium pump
    • provides energy for coupled transport of other molecules
    • produces electrochemical impulses in neuron and muscle cells
    • maintains osmolarity
  32. Important facts about Active Transport
    • ATP is needed
    • Low to High
    • goes against the Gradient

    • PUMPS
    • it uses ATP to build gradient and whn the time is right the door is open and floods out
  33. Important facts about Passive transport
    • No ATP needed
    • High to Low
    • Goes down the gradient
  34. Osmosis important to know
    solutes suck
  35. gradient and semipermeable membrane facts
    • solutes suck
    • Low to High Solutes
    • Dilute to concentrate
    • Hypotonic to Hypertonic
  36. cells that are in a hypotonic solution wil ___
  37. cells in a hypertonic solution will ____
    shrivel up
  38. depolarization is driven by
    the flow of Na+ into the cell
  39. when the membrane reaches 30 what happens

    • sodium channels are deactivated
    • at the same time Voltage gated channels are open and the potassium flows out of the cell
  40. difference between osmosis and diffusion
  41. what is depolarization
    when sodium goes in
  42. an action potential arriving at the axon terminals will stimulate the opening of voltage gate ion channels
