The graph below shows three plots of velocity (v0) versus substrate concentration ([S]). Determine which curve represents an enzyme's reaction velocity without any inhibitor present, which curve represents the velocity in the presence of a mixed inhibitor, and which curve represents the velocity in the presence of a competitive inhibitor.

Vo The graph below shows three plots of velocity (vo) versus substrate concentration ([S]). Determine which curve represents an enzyme's reaction velocity without any inhibitor present, which curve represents the velocity in the presence of a mixed inhibitor, and which curve represents the velocity in the presence of a competitive inhibitor. V Vmax Vmax no inhibitor Number = 3 5 competitive inhibitor mixed inhibitor continued below... [S] (M) Use data from the plots of vo versus [S] without an inhibitor and in the presence of a competitive inhibitor to calculate K when 6.0 M of the inhibitor is present.
