    Narrator: "...we have to be using a...?"
    Me: A phosphotase!
    Narrator: "Exactly, we're using a phosphotase"
    Me: Yay!! \o/
    Gotta love that XD Thank you very much, this video was great ^^

    Absolutely tremendous. Tip of the hat to you, Sal, and everyone else at Kahn Academy for the valuable public service you provide. Honestly the first donation I make 10 yrs from now when I'm an attending (fingers crossed lol) is to Kahn Academy. Medicine and science is visual. Books just don't do it for me. I'd be lost without you.

    teacher! you said that changing the enzyme wouldn't change the ▲G value .. but it changes the whole pathway .. I want to understand how the pathway is changed

      the EA is lower in the reverse process since the molecule is more stable in its latter form.

    phenomenal lecture... Gluconeogensis is so simple to me now, which I thought, was so complicated.

  • @felipepubillones2768
    @felipepubillones2768 9 років тому +4

    Now why couldn't you be this precise in the big picture video? Also, I cringed when you said the names of the first 2 enzymes were not important. They are very important since they are half of the unique ones!
    Would of been also nice to see you mention why a lack of glucose-6-phosphotase causes hypoglycemia. Glucose-6-phosphate is locked into a cell and can't pass the membrane since there is no transporter for it. Considering this is mostly used for MCAT review, a point like that is worth knowing. MCAT, and most medical school exams, are more of the "why" nature than "what."

    The fact that she misspelled fructose-1,6-bisphosphatase and then corrected it helped me to remember it.

  • @siulch7862
    @siulch7862 7 років тому

    Good video the only thing that you left out is that in the first step you need Acetyl Coa in the conversion of pyruvate to oxalacetate

  • @k1ngd0mh34rts1
    @k1ngd0mh34rts1 7 років тому +1

    you see for the second step is that meant to be "bi"phosphotase, and not "bis"phosphotase

    • @k1ngd0mh34rts1
      @k1ngd0mh34rts1 7 років тому

      nice she corrects it in the video,
      it's "bis"phosphotase

    • @Andrew-Davis
      @Andrew-Davis 6 років тому

      Good spot. Also, it's bisphosphAtase, not bisphosphOtase.

  • @b1boomergamer402
    @b1boomergamer402 9 років тому

    it's really good, but you forgot to mention the usage of the ATP to produce ADP in fructose 1,6 bisphosphate to fructose 6-phosphate and the last state to form Glucose.
    i hope you correct it. it could be sooo nice if you poste the pictures online after you comment on them. thanks for the amazing help.
