Hexokinase and glucokinase are both liver enzymes that
phorphorylate and trap glucose within the cell. The Km of
hexokinase for glucose is about 100 times lower than the Km of
glucokinase. What makes sense?
|
A. glucokinase traps glucose from blood in liver cells at lower
concentration than hexokinase, so that liver cells function under
fasting conditions |
|
B. glucokinase traps glucose from blood in liver cells at lower
concentrations in order to ensure production of glycogen for
storage |
C. |
hexokinase traps glucose from blood at a lower concentration in
order to store glycogen |
|
D. hexokinase traps glucose from blood at lower concentration
for cellular energy needs, while glucokinase traps glucose from
blood at higher concentrations for glycogen storage and other long
term metabolic needs |
