When vesicles containing glucose transporters come to the cell surface in liver cells after a high glucose meal, which of the following occurs?
A. glucose transporters are now in the plasma membrane
B. glucose transporters are released into the extracellular matrix
C. Transporters can now actively transport glucose across the membrane
D. more than one of the above answer is true.
Glucose transporters are transport proteins mainly concerned with glucose transport across cell membranes. They are the ones responsible in making sure that this fuel is contained within the cell where it can be processed for energy. Some glucose transporters are always present in plasma membranes but some are organized into vesicles which respond only to insulin.
