Glucokinase has low affinity for glucose. Glucokinase functions as the glucose sensor in the beta cell by controlling the rate of entry of glucose into the glycolytic pathway (glucose phosphorylation) and its subsequent metabolism. In the liver, glucokinase plays a key role in the ability to store glucose as glycogen, particularly in the postprandial state.
