Explain why glucose cannot pass directly through the cell membrane.

A. The plasma membrane is selectively permeable to all polar molecules and a transport protein is never required for them.

B. The plasma membrane is selectively permeable to polar molecules, and a transport protein is required for larger molecules.

C. The plasma membrane is impermeable to polar molecules, so transport proteins are required.

Final answer:

Glucose, being a polar molecule, needs transport proteins to cross the cell membrane.


Explanation:

Glucose cannot pass directly through the cell membrane because it is a polar molecule that cannot readily pass through the hydrophobic core of the membrane. Transport proteins, such as carrier proteins, are required to facilitate the passage of larger polar molecules like glucose across the membrane.
