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 concentratic
gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins chang
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?
A.
OB.
OC.
OD.
Blood cells take in glucose by active transport and intestinal cells take in glucose by passive transport.
