- Which of the following describes the function of cholesterols in plasma membranes to help regulate cell transport? Cholesterols are mainly responsible for cell signaling and cell recognition. Cholesterols act as fluidity buffer that make the membranes more fluid at higher B) temperatures and less fluid at lower temperatures. Cholesterols act as fluidity buffer that make the membranes less fluid at higher temperatures and more fluid at lower temperatures. Cholesterols in the phospholipid bilayer increase the membrane's permeability to ions and small molecules.Which of these general statements is TRUE about the lipid called phosphatidylethanolamine (or PE)? PE is zwitterionic at normal cell pH. PE is an aminophospholipid. 3 of these 4 responses are correct PE is a type of cholesterol.

Which of the following helps make the lipid rafts more stable and less mobile? phospholipid cholesterol sphingolipid a and b b and c
- Which of these general statements is TRUE about the lipid called phosphatidylethanolamine (or PE)? PE is NOT an aminophospholipid. 3 of these 4 responses are correct PE resides mainly in the outer leaflet of the membrane bilayer. PE is zwitterionic at normal cell pH. PE is a type of cholesterol.Membrane synthesis in the cell involves the movement of specific of phospholipids to the cytosolic face or non-cytosolic face (also known as extracellular face) of the membrane to achieve their mature distribution. Which enzyme non-selectively moves phospholipids between the two faces of the lipid bilayer? convertases flippases phospholipases scramblases floppasesWhich of the following molecules is more likely to diffuse through a synthetic lipid bilayer (i.e. a lipid bilayer without transmembrane transporters).
