In an vitro system, to study the glucose trasport in the intestina cell, a synthetic lipid bilayer membrane containing a specific glucose tranporter is suspended between to aqueous compartment, called X and Y.If the glucose conc. in X and Y is Equal but positive membrane is establised in the compartment X, net glucose transport occours from compartment X into compartment Y.which of the following transporter explain these results, and which compartment corresponds to the inside of the cell?? A.A glucose uniport,with compartment X corresponding to the inside of the cell B. A glucose uniport,with compartment Y corresponding to the inside of the cell C.A sodium glucose symport with compartment X corresponding to the inside of the cell D. A sodium glucose symport with compartment Y corresponding to the inside of the cell E. a voltage-gated glucose channel, with compartment Y corresponding to the inside of cell

In intestinal wall and PCT of nephronsthe glucose transporters are Na-Glucose symports .In rest of the body these are GLUTS (1,2 --------7)
None of them is voltage gated
Best of luck
