    dude i must say your videos really are the best. Usually I can't sit through anything longer than 10 minutes so with longer videos skip to where i can see the entire board so i have all the data i need, but your explanations are so well done that i sat through the entire video, without dosing off despite the fact that it's 3 am. Thanks again for the amazing lessons man, keep up the good work!

    Slight correction: for a competitive inhibitor higher km = decreased affinity for substrate

    • @jakephelps4766
      @jakephelps4766 2 ปีที่แล้ว +3

      you are essentially saying the same thing....in the last video he talked about how at 1/2vmax [s]=km so the km is basically telling you the concentration of substrate required to reach vmax....he talked about how basically increasing km results in decreased substrate affinity i.e you need to increase [s] to reach vmax

    @jeffersonfilberttjoenardi6644 5 ปีที่แล้ว +38

    I think something is off about the Competitive Inhibitor. If the Substrate Affinity goes up, the KM decreases, but as the Substrate Affinity goes down the KM increases. You explained that to beat the Competitive Inhibitor the Substrate Affinity must go up thus the KM will increase. No, I think the correct explanation is because the Competitive Inhibitor beat the Substrate's Affinity, the Substrate Affinity goes down hence the KM goes up. Because the effect of Competitive Inhibitor is KM goes up but Vmax unaffected. That's all from me, anyway amazing video! Really helps me understand difficult concepts!

    • @TheForeverFalcon
      @TheForeverFalcon 4 ปีที่แล้ว

      Why does the Km decrease of 'uncompetitive inhibition' then? How has the substrate infinity increased?

    • @chelsysagastume8296
      @chelsysagastume8296 4 ปีที่แล้ว +4

      yes, it's true the rise in Km means that there is a lower substrate affinity for the substrate and enzyme to make ES complex due to low km it takes for inhibitor as well as the high affinity for the inhibitor. So because enzyme has high affinity for the inhibitor it must be fixed. To fix it he has to increase the substrate concentration.

    Great explanation, nice job! But I am a bit confused here..... does this mean that in the presence of an irreversible inhibitor no catalysis will occur? I mean not at all? No matter the amount of substrate there is, non will bind to the enzyme? No effect on Km or Vmax?

    Hey I have a question, at 9:00 you said that the Km or the affinity that the enzyme has for the substance is increasing but if the Km increases due to increase in substance concentration shouldn’t the affinity decrease; sorry if I have any writing errors, English is not my native language 😅

    careful! at 8:56! from what i understand, km has an INVERSE relationship with affinity. what's written on the board looks fine but when you say "km, or affinity, increases" is not!

    • @RajKumar-xy3mr

    good explanation but I've got one question or one thing I don't understand. You said that when the substrate concentration will increase the Km will increase to and so the affinity. In the first part of the video you said that a high Km means that the enzyme has low substrate affinity. So how can the affinity become high in competitive inhibitor when the Km and substrate concentration increases?
