So, we were given a set of data of (uM) and the Velocity (umol/minute) of an inhibitor and no inhibitor. we are supposed to find the values of Vmax and Km in the absence of inhibitor and in the presence. do I use 1/Vo = 1/Vmax + Km/Vmax - 1/? but what is Km and the intial velocity? I'm sure this is fundamental for many, but the help would be appreciated.
