Which part of the cell membrane (phospholipid bi-layer) is attracted to water (hydrophilic), and which part hides from water (hydrophobic)? Identify the traits of molecules that can pass through the membrane, and predict which molecules can and cannot pass through.

What components of the plasma membrane might this molecule interact with?

Describe the molecular interactions that a cell uses to migrate through extracellular matrix. (use the key terms : actin, integrin, fibronectin)

Cholesterol has which of the following effects on the plasma membrane of an animal cell? it makes the membrane more rigid at low temperatures, and more fluid at high temperatures it makes the membrane more rigid at both low temperatures and high temperatures it makes the membrane more fluid at high temperatures, and more rigid at low temperatures it makes the membrane more fluid at both high temperatures and low temperatures it makes the membrane more fluid at low temperatures, and more rigid at high temperatures

Which three proteins participate in movement of vesicles from the plasma membrane toward the endosome? Group of answer choices Arf1, dyenin, tubulin COPII, tubulin, actin Sar1, cofilin, cadherins COPI, actin, kinesin

Which of the following statements is true about biomembrane?     Membrane proteins and lipids are distributed symmetrically in the two leaflets of the bilayer.     Lipid-linked proteins are anchored to the bilayer by the lipid moiety that covalently attached to the protein.     Lipid molecules can diffuse laterally in each leaflet of the bilayer but they can never flip from one leaflet to another.     The fluid mosaic model describes the dynamic arrangement and interaction of proteins but not lipids in membrane.     Bilayers are formed by triacylglycerol, glycerophospholipids, and sphingolipids.

The plasma membrane is composed of a variety of lipid molecules. 1. Phosphatidylethanolamine 2. Phosphatidylcholine 3. Phosphatidylinositol 4. Phosphatidylserine 5. Sphingomyelin 6. Glycolipids 7. Cholesterol. Which lipids contain sugar molecules?
