Why does the liver enhance glucose uptake after consuming a carbohydrate-rich meal?

Show Answers

Because glucokinase activity increases, leading to more glucose phosphorylationDue to insulin activating GLUT-2 transportersSince glucokinase exhibits a low Km value for glucoseBecause liver hexokinase has a strong binding affinity for glucose

Explanation

The liver's glucose uptake rises after a carbohydrate meal primarily because glucokinase activity increases, resulting in enhanced phosphorylation of glucose. This phosphorylation traps glucose inside liver cells, facilitating further metabolism. Other options are incorrect: GLUT-2 is not directly stimulated by insulin, glucokinase actually has a high Km (not low), and liver hexokinase does not have a high affinity for glucose.
