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?

In passive transport, no energy is required to transport the glucose molecules because they spon6tanosuely move down their concenntrati0n gradient. The transport protein in the blood cell membrane only enables the molecule to pass across the hydrophobic layer of lipid in the membrane and into the cell.

In active transport, energy is required in the transportation of glucose against their concentration gradient (glucose is highly concentrated in the lumen of the intestines than in the bloodstream). Sodium/Potassium (Na+/K+) pumps play a significant role in the transport of glucose. When sodium diffuses back into the cells, they drag along glucose molecules with them across the sodium-glucose transporter protein.
