    If no one else appreciates what you are doing on youtube, kindly know that I do, a thousand times. each time i find your lectures on a topic of interest I feel so happy because that topic is dead already. Thank you very much, continue to educate us. I watch almost all your videos

    your lectures have made me understand biochemistry so much more! I wish my professor could explain this half as well. All your enzyme lectures have been way helpful!

    Wow this is probably the best teaching video I've ever watched. Clear voice and slow talking speed so we have the time to comprehend what's going on, explaining stuffs once more just in case we don't watch previous videos, listing everything important down in a simple way so we can know what we'll be learning today and also easy to have a recap on. Bravo! You deserve more views than this.

    Hi sir thnkx for the hard work you are putting in your videos ... i have a question while we were deriving the equation of michaelis we said that when the time is nearly 0 the (Et)=(E)+(ES) but this time we said that when (S) is very low in comparison with Km we put (Et)=(E) ...isnt the same thing i mean when t is nearly 0 the concentration of the substrat is very low so how does is came that we end up with 2 differents equations ?? ... thnkx

  • @aishwiroshan4393
    @aishwiroshan4393 7 років тому

    When you wrote that Vo=kcat[ES] are you assuming that the substrate is at saturating conditions? Also, great video!

    greetings sir . we thanks you for your teaching. please I have a question to ask.
    please can u make a video on the differences between the Michaelis menten approach and the Brigg Haldane approach of enzyme kinetics. I can't really see a difference btw this two approaches

    IF I HAVE 2 X Km of substrat the V will be Vmax?

  • @Bite999
    @Bite999 9 років тому

    Hi! Is it correct to state that at [S]=Km we our [S]=[E]/2? Or does Km only state that the enzymes are working at half their capacity?

    • @AKLECTURES
      @AKLECTURES  9 років тому

      Remli Yusupov The Km value is a property of the enzyme under some specific conditions. So by stating that [S] = Km, you're basically stating that there is a certain amount of concentration in the environment at which the enzyme is working at half its maximum efficiency.

    • @tanvirahmed-rr7vt
      @tanvirahmed-rr7vt 3 роки тому +1

      as for a particular reaction , the amount of substrate molecule is much more higher than the amout of enzyme molecule. so therefore, you cant state that. (s)=(E)/2.
