Glucose is taken up by red blood cells by binding to a specific pocket in a membrane protein that then allows it to cross the membrane and move down its concentration gradient. What would be the best explanation of this process?

Facilitate diffusion by using a transporter

Explanation:

Facilitate diffusion is a type of transport in which a transporter protein is used to transport the molecule across the cell membrane along its concentration gradient. As the movement is along the concentration gradient and does not require energy so it is a type of diffusion.

Glucose travels in the cell by facilitating diffusion because it requires transporter to move across the cell along the concentration gradient. In facilitating diffusion the rate of transport in high than simple diffusion.
