Question

What is the unusual characteristic of cell membrane seen in apoptotic cell?

(a) Cell membrane ruptures

(b) Cell membrane channels stop working

(c) Cell membrane exposes phosphatidyl serine on the outer side

(d) Cell membrane exposes the cholesterol and lipid rafts on the outer side

I have been asked this question in quiz.

I'm obligated to ask this question of Apoptosis and Cancer in section Cancer Biology & Methods in Cytogenetics of Cytogenetics

Answer 1

The correct option is (c) Cell membrane exposes phosphatidyl serine on the outer side

For explanation: Phosphatidyl serine is mainly present on the inner side of the cell membrane, this is seen in the outer side of the apoptotic cell membrane that encourages phagocytosis.
