Hexokinase and glucokinase both catalyze the phospkorylation of glucose to glucose 6-phosphate. The values of Km for the enzymes are 10uM and 0.02M, respectively. If blood glucose is 5 mM under fasting conditions and 20 mM after a high carbohydrate meal:
A. Hexokinase will function near its Vm under fasting conditions
B. Glucokinase will function near its Vm under fasting conditions
C. Hexokinase will function at less than one-half Vm after a high-carbohydrate meal
D. Glucokinase will function at less than one-half Vm after a high-carbohydrate meal
