(1 point) The Michaelis-Menten equation describes the initial velocity of an enzymatic reaction. The equation is Vo UmaxSo So + Km where U is the initial velocity of the reaction, So is the initial concentration of the substrate, Umax is the maximum velocity at which the product may be formed, and Km is the Michaelis-Menten constant. As the initial concentration gets arbitrarily large, what happens to the initial velocity of the reaction? lim Vo= (Your answer may include the variables "vmax" and "Km".)
