Glucose provides energy for cells. different cells have different mechanisms for glucose intake. intestinal cells contain proteins that transport glucose against its concentration gradient. these proteins couple the movement of glucose to the movement of sodium down its concentration gradient. red blood cells have transporter proteins embedded in their membranes. when bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell. based on this information, what type of transport is used for glucose in blood and intestinal cells?
