Lipid rafts are specialized microdomains within the plasma membrane that are rich in cholesterol and sphingolipids. These regions play critical roles in cellular signaling, protein sorting, and trafficking. They are more ordered and tightly packed than the surrounding membrane but still maintain fluidity.
Phospholipid vesicles prepared in 50 mM KCl were diluted in water. Based on this information, statements P and Q are made.
P: The diluted vesicles will develop membrane potential.
Q: There is a K+ concentration difference across the vesicular membrane.
