    Your 6mins video is so much more useful and helpful than my teacher’s 60mins talking. Thank you ever so much🙏🏼your videos are great please continue to make some more☺️

    Thank you, you've really cleared this up for me, I was struggling to get this concept without a visual demonstration and yours is excellent. Now I have just explained it out loud and managed to slowly but surely recite the whole process! :)

    At 2:12, you wrote NADP donates a proton to gp and hence the gp is reduced. Are you referring to the reduction as in donating electrons? Because isn't reduction the gaining of electrons, not protons.
    Also, your videos are so useful. Thank you!

    • @BioRach
      @BioRach  3 ปีที่แล้ว +1

      By reduction I meant the reduction of GP to TP. Reduction is the gaining of hydrogen and/or electrons! :) Hope this clears things up and thanks for watching!

    This is such a useful video thank you so much!! I do have one question, for the electron carrier and the EC in the diagram are they the same thing or is the EC the electron transport chain?

    • @BioRach
      @BioRach  3 ปีที่แล้ว +1

      EC is just my shorthand for electron carriers! All of them together forms the electron transport chain. Hope this clears it up and thanks for watching! :)

    Amazing video as always, I was just wondering is there a reason when would the plant choose use cyclic photophosphorolation or non cyclic phsophophorolation, thanks

    • @BioRach
      @BioRach  ปีที่แล้ว

      The plant may opt for cyclic photophosphorylation if it's lacking in ATP! Keep in mind that the light-independent stage requires ATP for the conversion of substrates, so it can't do that if there isn't enough ATP.

    Hiya, I'm just a little confused so after the Electron transport carrier from Photosystem II is there another ATP synthase like the one at the end (after the ECT from PSI) which is what produced the ATP?

    • @BioRach
      @BioRach  3 ปีที่แล้ว +1

      Yes! There are multiple ATP synthases along the membrane, so there would be some found after each ETC.

      It's 1/2 an oxygen molecule, so really just an oxygen atom, since there's only one per water molecule! Hope this clears it up and thanks for watching :D
