Glucose is a large molecule that cannot penetrate the phospholipid bilayer of cells. Instead, glucose enters most cells through

special carrier proteins embedded in the plasma membrane. In doing so, glucose moves from an area of high concentration to an area of low concentration. Based on this information, which term best describes the uptake of glucose by cells?

The term is Facilitated diffusion.

Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.

The energy is provided by the concentration gradient, which means that molecules are transported from higher  to lower concentrations, into or out of the cell.

The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.

Red blood cells use facilitated diffusion to absorb glucose.
