Question

Quizplus · Accepted Answer

Aquaporins are specialized channels that allow for the efficient movement of small, hydrophilic molecules such as water and glycerol across cell membranes. Cholesterol, beta carotene, and vitamin D are hydrophobic molecules and would not be able to pass through an aquaporin. Glucose is a larger molecule that typically requires specific transporters for entry into cells.
