Current Question (ID: 12655)

Question:
Neutral solutes directly pass through the lipid bilayer of plasma membrane because
Options:
  • 1. Plasma membrane has special carrier for them
  • 2. They are lipid soluble
  • 3. They have specific hydrophilic areas for their passage
  • 4. They consume ATP
Solution:
Neutral solutes directly pass through the lipid bilayer of plasma membrane because they are lipid soluble. The lipid bilayer of the plasma membrane is composed of two layers of phospholipids, which have hydrophilic heads and hydrophobic tails. Neutral solutes that are lipid-soluble, such as oxygen and carbon dioxide, can easily pass through the hydrophobic tails of the phospholipids, and do not require special carriers or consume ATP.
