Aug 22, 2016 · Kcat = turnover of substrate to product / unit time. Kcat/Km = measure of catalytic efficiency. You use this if the question is asking about which enzyme has the greatest …

Aug 12, 2020 · The [S] terms cancel, which is why at saturating conditions, Vo = Vmax. Since kcat is a decent surrogate for Vmax here, what this means is that kcat tells us roughly how well the …

Jul 11, 2021 · Vmax =Kcat[E] Catalytic efficiency = Kcat/Km *greater this value, more efficient the enzyme Hill coefficient > 1, positive cooperative binding Hill coefficient < 1, negative …

Aug 7, 2019 · Thinking about what Kcat is helps me remember how to calculate it. Kcat as the turnover constant describes the max amount of product formed per enzyme, per second. If you …

Jun 11, 2017 · The #1 social media platform for MCAT advice. The MCAT (Medical College Admission Test) is offered by the AAMC and is a required exam for admission to medical …

Aug 22, 2017 · Kcat is the number of substrate molecules/time that a enzyme can do. It's the turnover number. Km is the affinity an enzyme has for a substrate. It is measured as being the …

May 23, 2020 · Kcat is a ratio, and we know that Vmax and total enzyme concentration are directly proportional to one another. This means that if you double total enzyme conc, you will …

May 25, 2021 · The definition of catalytic efficiency is kcat/Km. So to have a high catalytic efficiency, you want a large numerator (large kcat) and/or a small denominator (small Km). …

May 2, 2022 · Kcat describes catalysis higher Kcat means better catalysis. Km is kinda weird but you can kinda think of it has the warm up time. The bigger the Km that more substrate that …

Nov 15, 2019 · What would be the Kcat (turnover number or molecular activity) of the enzyme under these conditions? I started by laying out everything I know: Kcat = Vmax/[E] in s-1 or …
