Certain Phospholipids, Including ____ and ____, Participate in Complex Cellular

Question

Certain phospholipids, including ____ and ____, participate in complex cellular signaling events.
A) phosphatidylcholine; phosphatidylserine
B) phosphatidylserine; phosphatidylalanine
C) phosphatidylcholine; phosphatidylglycerol
D) phosphatidylinositol; phosphatidylcholine
E) phosphatidylethanolamine; phosphatidylserine

Accepted Answer

Phosphatidylinositol and phosphatidylcholine are both phospholipids that participate in complex cellular signaling events. Phosphatidylinositol is a precursor for important signaling molecules such as inositol trisphosphate and diacylglycerol, while phosphatidylcholine is involved in numerous signaling pathways including activation of protein kinase C and modulation of ion channels.
