Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? A) Sodium and glucose bind to the same site on the cotransporter.

C) Sodium ions can be transported whether or not glucose is present outside the cell, but glucose transport requires cotransport of sodium ions. D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient. E) Following transport of sodium ions into the cell, the cotransporter can also transport potassium ions out of the cell.
