Based on the Lineweaver-Burk plot shown below, which statement is true? KM=2mM,Vmax=0.2mmol/min KM=2mM,Vmax=5mmol/min KM=0.5mM,Vmax=5mmol/min KM=2mM,Vmax=5mmol/min KM=2mM,Vmax=5mmol/min When an enzyme obeys the Michaelis-Menten kinetics, and when the substrate concentration is much greater than KM, which statement is true? The reaction is second-order with respect to S The reaction is first-order with respect to S The enzyme becomes an allosteric enzyme The reaction is zero order with respect to S Such situation is not possible - substrate concentration cannot be much greater than KM
