The “mean-speed theorem” for calculating average velocity under constant acceleration, developed by Thomas Bradwardine and the Mertonian Calculators at Oxford University, is expressed algebraically as:
density = weight/volume
(m1)(v1) = (m2)(v2)
C. (vm) = 1/2 (v0 + vf)
s = (v0)(t) + 1/2 (a)(t2)
velocity = distance/time
Using the Michaelis-Mentan graph pictured (graphing initial velocity and PNPP concentration), identify Vmax and Km as well as possible. Then, using the Lineweaver-Burk graph (graphing 1/Vo and 1 / PNPP concentration), label the reciprocals of Vmax and Km on the graph and use them to calculate Km and Vmax.
why is the maximum velocity in the michaeli's equation not touching the rectangular hyperbolic curve
