Plasma Membrane: Models and Transport · Zoology

The asymmetrical distribution of lipids and proteins in the plasma membrane contributes to:

  1. Loss of membrane integrity
  2. Membrane rigidity
  3. Functional specialization
  4. Random molecular movement
Show answer and explanation

Correct answer: Functional specialization

Asymmetry in membrane components allows different surfaces of the membrane to perform distinct functions. This is essential for processes like cell recognition, signaling, and directed vesicle trafficking.
