Problem 15: Interpreting the plateau of an enzyme kinetics curve


In the graph reaction rate vs substrate concentration, the reason that the curve reaches a plateau, and does not increase any further at high substrate concentration is that:
A. the active site is saturated with substrate

B. there is a competitive inhibitor present

C. there is a non-competitive inhibitor present

D. the allosteric enzyme is locked in an inactive conformation

E. all substrate has been converted to product
