Which substances can cross the plasma membrane more easily?
Correct answer: B. Soluble Lipids
- A. lons
- B. Soluble Lipids
- C. Proteins
- D. Starch
Explanation
Soluble lipids have the highest likelihood of crossing the plasma membrane more easily due to them being easily diffusable . Small proteins, and small molecules like oxygen and carbon dioxide can also pass through the lipid bilayer to some extent. Large molecules such as starch require more specialized mechanisms for transport across the plasma membrane.
