To study the nature of an enzyme, V_max is not as good a measurement as the catalytic rate constant k_cat because: A) The V_max is not a true constant since it depends on the concentration of enzyme B) The V_max cannot be measured C) The V_max is only valid for allosteric enzymes D) none of these

Question

Quizplus · Accepted Answer

The $V_{\text{max}}$ is not a true constant because it varies with the concentration of the enzyme, making it less reliable for studying the intrinsic properties of an enzyme compared to the catalytic rate constant $k_{\text{cat}}$, which is independent of enzyme concentration.
