Question

Which of the following is an amphipathic molecule in plasma membrane?

• A. Protein
• B. Carbohydrates
• C. Phospholipids
• D. All of the above

Answer 1

The correct option is C Phospholipids

The lipids in the plasma membrane are phospholipids with one polar hydrophilic head and two nonpolar hydrophobic tail. Thus, the lipids are amphipathic. The hydrophilic head is exposed to the surface whereas the hydrophobic tail is embedded in the inner region of the membrane.

So, the correct answer is option C.
