Question:

Which of the following is not true for cell membrane?

Show Hint

Carbohydrates form glycoproteins and glycolipids in the cell membrane, essential for cell recognition (glycocalyx).
Updated On: May 26, 2026
  • Phospholipid is an amphipathic molecule
  • Phospholipid has both a hydrophilic region and a hydrophobic region
  • Membrane proteins can reside in phospholipid bilayer with their hydrophilic regions protruding
  • Carbohydrates are totally absent in the cell membrane

The Correct Option is D

Solution and Explanation


Step 1: Concept

Cell membrane structure and composition (Fluid Mosaic Model).

Step 2: Meaning

The cell membrane contains phospholipids, proteins, cholesterol, and carbohydrates.

Step 3: Analysis

(A), (B), and (C) are all true statements about the cell membrane. Option (D) is false: carbohydrates are present in the membrane as glycoproteins and glycolipids, playing important roles in cell recognition and signalling.

Step 4: Conclusion

Option (D) is not true --- carbohydrates are indeed present in the cell membrane. Final Answer: (D)
