The following graph represents effect of substrate concentration on the initial velocity of an enzyme catalyzed reaction. Wrong statement about this graph is:

This is Michaelis Menten graph (rectangular hyperbola shape). Km is Michaelis Menten constant. Km is that substrate concentration at which velocity of reaction is half of Vmax. Here '?' point represents Km (on X-axis). At point C, maximum amount of enzyme is present as E-S complex --- so option C is wrong Initial poion of this graph has first order kinetics i.e. velocity is directly propoional to substrate concentration Later poion of the graph has zero order kinetics i.e. velocity is independent of substrate concentration
