Question
A nonpolar molecule will move across a semi-permeable membrane more rapidly than a polar molecule.
Group starts True or False
Solution
Answer Explanation
-
Understanding the Concepts: Nonpolar molecules are generally more soluble in lipids (fats) than in water, while polar molecules are hydrophilic and tend to dissolve in water. A semi-permeable membrane is often composed of a lipid bilayer that allows certain molecules to pass through while blocking others based on their properties.
-
Membrane Interaction: Nonpolar molecules can easily pass through the hydrophobic interior of the lipid bilayer due to their compatibility with lipids. In contrast, polar molecules struggle to cross the membrane because they cannot effectively interact with the nonpolar interior.
-
Conclusion: Since nonpolar molecules can traverse the membrane more readily than polar molecules due to their solubility properties, the statement holds true.
Final Answer
True
