Which of the following molecules would likely diffuse through the lipid bilayer of a plasma membrane most rapidly? A) sucrose B) an amino acid C) O₂ D) Na+

Question

Quizplus · Accepted Answer

Molecule C, represented by the chemical formula O₂, is likely a simplified representation or error in transcription. However, based on the context of the question, it is implied that this molecule is nonpolar or small enough to rapidly diffuse through the lipid bilayer of a plasma membrane. Nonpolar molecules and small uncharged molecules can pass through the lipid bilayer more easily than ions (like Na+) or larger polar molecules (like sucrose and amino acids).
