Question

Which of the following statements is false for an enzyme that follows Michaelis-Menten kinetics?

A. The Michaelis-Menten equation assumes that ES maintains a steady state.

B. Maximal velocity occurs when the enzyme is entirely in the ES form.

C. The initial velocity of the reaction is dependent on substrate concentration.

D. The relationship between substrate concentration and reaction rate is sigmoidal.

I tried A and B and they were wrong. Can someone please help and explain this to me?

A. The Michaelis-Menten equation assumes that ES maintains a steady state.
