Explain why glucose cannot pass directly through the cell membrane. a. The plasma membrane is impermeable to polar molecules, so transport proteins are required. b. The plasma membrane is selectively permeable to polar molecules, and a transport protein is required for larger molecules. c. The plasma membrane is permeable to all polar molecules, but a transport protein is required. d. The plasma membrane is selectively permeable to all polar molecules and a transport protein is never required for them.

Glucose transporter is a membrane protein that enables glucose to move across the cellular membrane from the extracellular side to the intracellular side. It is classified as a passive transport protein, allowing for facilitated diffusion across the membrane. What does this information tell you about the relative intracellular and extracellular concentrations of glucose? Does this make physiological sense? Why or why not? What strategies do cells use to keep the intracellular concentration of "glucose" high yet allow for passive facilitated diffusion of glucose into the cell?
