    I attend a major university for plant science, and this video has helped me much more than my professor.....

      Glad you like it! This diagram has been a couple of years in the works and has gone through many different test versions with input both from other teachers and my high school students. Somewhere along the line, one of my students had the idea for NADPH to look like a truck, for instance. The version that I now use is similar but not identical as I'm always tinkering with new approaches. Good luck!

    I've watched several videos trying to understand this and didn't get it. Something about this video made it click! Thank you so much!!

      So glad it was useful! I'm considering doing a remake of this video to make a few things more clear. Let me know if you have any feedback (besides the egregious microphone noise!!) -BOGO

    i'm having a marathon on your videos because why not they are worth it.

    Thankyou soooooooooo much! You're a lifesaver, it makes so much more sense now. You now have a new subscriber, I'll be looking forward to other videos that you make.

      Thanks, Strike! Working on a new video on cellular respiration. Hoping to have it out just in time for the start of school here in the US. Take care! -BOGO

    but, girl.... please, do something with the microfon noize.... :D

      Not the first person to point this out! I realize it's a pain; I've invested in a mic since making this; at some point I'll redo it!

    Hi there, I am learning a lot through these videos as I study for biology. I was wondering if you had a template to download the diagram?

    • @BOGObiology
      @BOGObiology  6 років тому

      Hi Herman! I'm so glad you're finding them helpful. I actually used to have a blank diagram that I made for my students. I'll see if I can track it down this afternoon. Good luck!

    Nice video once again but here is a question;
    1) During the formation of PGAL does the NADPH and ATP decompose to provide protons,electrons and inorganic phosphate,energy respectively to the PGA or there is something else going on?

    • @BOGObiology

      Hello again!
      This is one of those videos that really has to be watched start to finish; it's no good in little chunks, the process is too complicated.
      NADPH is depicted here as a dump truck (one of my students came up with the idea) because it delivers components to the Calvin Cycle from a previous set of chemical reaction. Once it has "dumped" those components, it has to be refueled by the Light Independent reactions. Notice how the truck is labeled NADP+ and is empty on its way back. Look carefully, and you'll figure out what it "delivered"
      ATP also functions as a carrier molecule of sorts, but I'm not telling you what it delivers, because I bet you can figure it out. Look at what goes into the energy bubble from the step before it and from NADPH. Then use process of elimination.
      If you watch the whole thing and think carefully, the pieces should start to come together. Let me know how you fare!

    where does the oxygen molecule end up after the carbon is used from the carbon dioxide molecule?

      It's given off as a waste product, luckily for us!!!

    The description, and center of the video cycle, describes the Calvin Cylce as light dependent. this should be the opposite: light independent.

    • @BOGObiology
      @BOGObiology  7 років тому

      You are right about the description, that was a typo, and I'm glad you pointed it out. HOWEVER, the video depicts how the products of the light DEPENDENT reactions are used in various parts of the light INdependent reactions. Hence, the ATP and NADPH emerging from it to be used in various parts of the Calvin Cycle. I tried it a number of other ways and the diagram simply "works" better this way. Hope this clarifies -BB

    Really like all of your videos but it is really annoying to hear this sound in the background of you moving around. I can't even concentrate on what you say because it agrevates me so much

    • @BOGObiology
      @BOGObiology  7 років тому

      Sorry to hear that, I realize it's a complete pain. This is one of my earliest videos before I started using a headphone mic to record my stuff. You'll notice the new ones are better!

      Maybe someday! Unfortunately, I don't speak Hindi! I also made a new version of this video: ua-cam.com/video/ZKC_aRrf1Rg/v-deo.html Sending love and best wishes from Boston! -BOGO
