    @7:05 How does NADH give off two hydrogens? It isn’t balanced.

    I have a question
    You mentioned that the first step of the cellular respiration happend in cytoplasm with mean pyruvate need to get inside the matrix to start the 2 step BUT you also mention that the inter membrane is NOT preamble right . And the only way for the pyruvate to get into matrix is to go through the ATP syntase. How is that possible ?

    • @anoodchoudhary6101
      @anoodchoudhary6101 4 года назад +4

      There are porins on the outer membrane of mitochondria... Which are the multipass transmembrane proteins (transport proteins) and through them the pyruvate enters the mitochondria

  • @miyamaha5

    I have a two questions: 1) Can the hydrogen ions pumped into the inter membrane "leak" out of the outer membrane into the cytosol? 2) How does ATP leave the mitochondria in order to go to other places in the cell where it is needed? Thank you!

    If the outer membrane is permeable to H+, how can the inter membrane space maintain such a low pH? Wouldn't the H+ ions travel down their concentration gradient from the inter membrane space out into the cytosol?

  • @lordango
    @lordango 8 лет назад +5

    i thought you said inner membranes are not permeable? how did the H ions got out from the matrix? im a computer programmer btw, i have no idea how i got here

    • @masoudmousavi2571
      @masoudmousavi2571 8 лет назад +2

      the inner membrane has got specialized proteins that can pomp out ions such as H+

    FYI there will be a bunch of copies of the genome in each mitochondrion and a bunch of mitochondria in each cell...

    why is nadh creating 2 H+? Did she make a mistake?

    • @teobestoffer1165
      @teobestoffer1165 8 лет назад

      +Stefan Thorarensen I think it should just be H+... then the equation will be balanced in both charges and atoms

    Absolutely love Khan academy! But I wish Sal would do all the videos - I literally skip all the videos that are not done by him. And the reason for that is because these ones, done by this lady. are bloody monotonous. Amazing knowledge but seriously...annoys the hell out of me. Whereas when Sal does the videos, you can tell that he is actually super interested and fascinated by the things that he talks about- and that’s how it should be. Loving the stuff that you learn about and teach.

    Nice, I'm one step closer to becoming a doctor and making bank so I can buy nice stuff, and then find some hot gold digger chick who i'll make sure to not marry so when we split she doesn't take half my money. Then I'll just continue on with my life by going into work, seeing patients and writing them prescriptions, and I can forget 90 percent of what I learned in school because it's not applicable to the actual practicing of medicine.
