Question

GLUT 4 Transporters:

a. inserted in response to glucagon

b. found in liver and skeletal muscles

c. inserted into the plasma membrane by endocytosis

d. stored in cytoplasmic vesicles.

Answer 1

GLUT4 transporters are proteins that binds to glucose in presence of insulin and moves the glucose into the cell.

GLUT4 transporters are inserted into the plasma membrane in presence of insulin not glucagon. So statement A is incorrect

GLUT4 transporters protein are found in skeletal muscles, cardiac muscles and adipose tissues along with liver. So statement b is incorrect

GLUT4 transporters are released through exocytosis. So statement c is incorrect

GLUT4 transporters are found in the cytoplasmic vesicles. So statement d is correct.
ANSWER : D
