    i've just missed about 3 lesson on this reaction due to corona and you've just explained it in 12 mins. an angel. thank you so so much!

    this video was so helpful! it made so much easier to understand. I wish you did one on the Calvin cycle thou.

      I have made a video on the Calvin cycle - I actually have a lesson covering every aspect of the new spec for biology, as well as all the videos like this one I do live classes every week and answer all your questions every day. You can see it for yourself here tailoredtutors.co.uk/free-trial/

      Hey Megan, I have recorded a lesson on every single part of the A-Level spec for AQA, OCR and Edexcel! It coaches you on how to learn the content as quickly as possible plus I'm on hand to answer all your questions (24 hr turnaround time) as well as the right exam technique to use in the exams. FYI It's not free though as it's my full time job!

    Is the pumping of H+ ions against their concentration gradient considered to be in photosystem I or II?

    • @tailoredtutors
      @tailoredtutors  4 роки тому +1

      It's part of the electron transport chain so it's both as the electrons flow from PS II to PS I via the electron carrier proteins in the thylakoid membrane.

  • @nibahasaf
    @nibahasaf 7 років тому

    When the electron go down the chain releasing energy, is it used to form ATP or pump the H+ into the thylakoids space?

    • @keanudaboy1383
      @keanudaboy1383 7 років тому

      Both

    • @keanudaboy1383
      @keanudaboy1383 7 років тому +4

      The energy is used to pump H+ ions into the thylakoid space and the movement through ATP synthase via chemiosmosis provides the energy to produce ATP.

    Might sound like a silly question.
    When does the photolysis of water occur? As soon as the light energy has been absorbed? Or simultaneously while all the other reactions are happening??

      @Momo8 6 років тому +1

      @@tailoredtutors non cyclic photophosphorylation uses both PS2 and PS1. It creates O2 and NADPH in comparison to Cyclic p. which only uses PS1 and does not create O2 and NADPH
