The Michaelis-Menten assumptions are integral to

understanding the kinetics of enzyme-based reactions. Which of the following is NOT one of

these assumptions?

W) Substrate is present in slightly greater quantities than the enzyme

X) In a steady state, the concentration of the intermediate is always constant

Y) Rate is highest when enzyme catalytic sites are saturated with substrate

Z) The reaction between the substrate and the enzyme is reversible
W) SUBSTRATE IS PRESENT IN SLIGHTLY GREATER QUANTITIES THAN THE ENZYME
