- Although both faces of a biomembrane are composed of the same general types of macromolecules, principally lipids and proteins, the two faces of the bilayer are not identical. What accounts for the asymmetry between the two faces?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.What is meant by isotonic, hypotonic, and hypertonic in terms of a solution surrounding a cell membrane?
- Why is it advantageous for the cell membrane to be fluid in nature?Distinguish between the following pairs of terms: a. diffusion; osmosis b. passive transport; active transport c. endocytosis; exocytosisWhat does the fluid part of the fluid mosaic model represent? a. Constant movement of the hydrophilic tails in the interior of the membrane b. The thin layer of water that is sandwitched between the to layers of lipids c. Lipid molecules, which freely move among other lipids within the same half of the bilayer d. Free movement of cholesterol molecules within the membrane
- Which molecule would you predict moves through a lipid bilayer most rapidly without the help of a transport protein? Group of answer choices A NH2SO2CH3 B C6H12O6 C C2H4 D CH3OH E C2H5OHWhat are components of the fluid mosaic model of the cell membrane? A. The cell membrane is a lipid bilayer with molecules such as cholesterol and proteins embedded in it. B. The lipid bilayer is a solid structure held together by chemical bonds. C. The cell membrane is a lipid bilayer with no other molecules embedded in it.Why can nitrogen cross the membrane via diffusion through the bilayer and while protons require a protein?
- Which of the following is true about phospholipid bilayers? The interior of the layer is highly hydrophilic. The hydrophobic tail faces the cell interior. The polar/hydrophilic tails face the cell interior and exterior. The polar/hydrophilic heads face the cell interior and exterior. The hydrophobic head faces the cell exterior.It seems paradoxical that a lipid bilayer can be fluid yet asymmetrical. Explain.Define the following terms: a. osmosis b. osmotic pressure c. membrane potential d. isotonic solution e. structured water
