Which of the following scenarios could enhance enzyme activity of hexokinase (an enzyme that phosphorylates glucose via ATP catabolism in the cytosol)

• Hexokinase is ubiquinated

• More GLUT2 (a glucose transporter) is inserted into the cell membrane

• More ATP becomes available

• Phosphorylated glucose accumulates in the cytosol (high concentration)

More GLUT2 is inserted into the cell membrane

More ATP becomes available
