Where are the phosphatidylserine residues in the plasma membrane are located?
Correct answer: B. Inner leaflet of the plasma membrane
- A. The outer leaflet of the plasma membrane
- B. Inner leaflet of the plasma membrane
- C. Evenly distributed in the inner and outer leaflet
- D. None of these
Explanation
Option B is correct since in normal cells, 'phosphatidylserine residues' are found exclusively on the inner side of the cellular membrane. During 'apoptosis', phosphatidylserine is transported to the outer cell surface.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
