Question

diffusion of glucose into rbc is an example of what type of membrane transport?
diffusion
facilitated diffusion
active transport
simple diffusion

Explanation:

Glucose is a polar molecule and cannot pass through the non - polar lipid bilayer of the RBC membrane easily. It requires a carrier protein for transport. Facilitated diffusion uses carrier or channel proteins to move substances down their concentration gradient without the use of energy. Glucose enters RBCs down its concentration gradient with the help of glucose transporters (GLUTs), which is facilitated diffusion.

Answer:

Facilitated diffusion
