Would you explain me about how phospholipidserine can move from extracellular side to intraselular side in apoptosis mechanism.
That's all my question. Thanks for your attention.

A teacher will say easy! In fact, it's not so easy :D
The phenomenon in known as tranversal diffusion or Flip-Flop. It is an unfavorable phenomenon from an energetical point of view- it requires energy. A membranar enzyme called flipase or phospholipidtranslocase(long name, isn't it?!) rraps the phospholipid in a hidrophobe pocket(couldn't find a better word) and then moves it on the other side...
PS: you don't need to present yourself...
