GLUT2 GLUT2 is a bidirectional glucose transporter that is expressed in pancreatic islet cells, the liver and the kidney. It does not translocate to the cell membrane with exercise. GLUT3 GLUT3 is primarily expressed in neurons and does not translocate to the cell membrane with exercise. GLUT4 GLUT4 is an insulin-responsive glucose transporter found in adipose tissue and muscle that translocates to the cell membrane upon exercise. GLUT5 GLUT5 is a fructose transporter expressed on the apical border of enterocytes in the small intestine. It does not translocate to the cell membrane with exercise. Biochemistry William J Gibson (Reviewed by Serge Korjian) A scientist is studying the mechanism of exercise-induced insulin sensitivity in diabetic patients. A biopsy of the vastus lateralis muscle is obtained from a patient's left leg at rest. Three to six weeks later, the subjects performs 60 minutes of cycling at 70% VO₂ max, and immediately thereafter another biopsy is obtained from the right vastus lateralis muscle. The investigator performs immunohistochemistry for both obtained tissues. Which of the following will demonstrate increased localization to the plasma membrane?
