ENZYMOLOGY

A teenager finishes eating a hot fudge sundae and a milk shake. As her blood sugar rises, the liver recruits both Glucokinase (km = 10.0m M) and Hexokinase (km = 0.10mM) to metabolize the glucose. Which of the following is a correct statement about the kinetics of these two enzymes?

A. Hexokinase will metabolize 100 times more glucose molecules

B. Hexokinase will lower the energy of activation more than glucokinase

C. Hexokinase has a much higher affinity to glucose than glucokinase

D. Hexokinase will have a higher Vmax than glucokinase

E. Hexokinase will be induced more than glucokinase by the rising concentration of glucose

  1. E but maybe A. No probably just E, bc it has a higher affinity (km)
