Question

Given the composition and behavior of imbalance as you know it the accepted model that accurately describes the structure of the membrane is that It is a solid mosaic containing a double lipid bilayer It is a gaseous mosaic containing a double bilayer It is like wax containing only proteins on the double bilayer It is a mosaic on a lipid bilayer interspersed with proteins It is all cholesterol mixed with proteins on a double bilayer Membrane lipids may have the following properties except spontaneously flip-flop from one membrane leaflet to the other move laterally within one membrane leaflet be unequally distributed in the two membranes leaflets be present in varying amounts in different cellular membranes Movement of phospholipids from one leaflet to the other occurs routinely requires cholesterol requires lipases is impossible. Although all membranes are selectively permeable. the specific function of a particularly membrane is due to the phospholipid composition the carbohydrates composition the nucleic acid composition the origin of the particular membrane in question the protein composition According to the fluid mosaic model of membrane structure, proteins of the membranes are mostly spread in a continuous layer over the inner and outer surfaces of the membrane confined to the hydrophobic core of the membrane embedded in a lipid bilayer randomly oriented in the membrane, with no fixed inside-outside polarity free to depart from the fluid membrane and dissolve in the surrounding solution Integral membrane proteins lack tertiary structure are loosely bound to the bilayer are usually transmembrane proteins are not mobile within the bilayer have no known functions in membranes

Explanation / Answer

24)(d) it is a fluid mosaic on al lipid bilayer interspered with proteins.

25)(c)be unequally distributed in the two membrane leaflet.

26)(c)requires flippases.

27)(e)protein composition.

28)(c)embedded in a bilipid layer.

29)(c)are usually transmembrane proteins.
