Insertion of ______________ in the muscle cell membrane increases cellular glucose uptake.
A)GLUT1
B)GLUT2
C)GLUT3
D)GLUT4

Question

Quizplus · Accepted Answer

GLUT4 is the glucose transporter present in muscle cells, and its insertion in the cell membrane is responsible for increasing cellular glucose uptake. This process is stimulated by insulin, which signals the insertion of GLUT4 transporters into the cell membrane, allowing glucose to enter the cell and be used as energy or stored as glycogen. GLU1 and GLUT3 are expressed in other tissues, while GLUT2 is mainly present in liver and pancreas cells. Therefore, D) GLUT4 is the best choice for this question.
