Membrane Fluidity. There are multiple factors that lead to membrane fluidity. First, the mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist in the membrane as separate but loosely-attached molecules. The membrane is not like a balloon that can expand and contract; rather, it isWhich of the following factors would tend to increase membrane fluidity? (A) a greater proportion of unsaturated phospholipids (B) a greater proportion of saturated phospholipids (C) a lower temperature (D) a relatively high protein content in the...Which of the following factors would tend to increase membrane fluidity? A)a greater proportion of unsaturated phospholipids B)a greater proportion of saturated phospholipids C)a lower temperature D)a relatively high protein content in the membraneThe fluidity of the phospholipid bilayer depends on different factors like the length of the fatty acid chain, the temperature, the cholesterol content, and the level of saturation in the layer. As the amount or number of unsaturated fatty acids increases in the bilayer, so does the fluidity.Play this game to review Nervous System.

(Solved) - Which of the following processes includes all
Cell membranes having "fluid" nature means (they are dynamic in changing their position and adaptive to amorphous shapes). Factors affecting fluidity of membrane:- 1- Temparature:- Higher temperature disbalances the integrity of adjacent molecules...Ans. 7 Membrane fluidity depends upon temperature, length and saturation level of fatty acids in phospolipids, and presence of cholesterol. At low temperature, membrane becomes fluid and with increa view the full answer Previous question Next questionB) confined to the hydrophobic interior of the membrane. C) embedded in a lipid bilayer. D) randomly oriented in the membrane, with no fixed inside-outside polarity. E) free to depart from the fluid membrane and dissolve in the surrounding solution. Human immunodeficiency virus (HIV) infects cells that have both CD4 and CCR5 cell surface molecules.Unsaturated phospholipids high proportion will likely increase the membrane fluidity because unsaturated fatty acids cause a twist in their tail forming some gap between the molecules of the phospholipid bilayer. This small gap will maintain membrane fluidity at temperatures in which saturated phospholipid molecules get freeze.

Which of the following factors would tend to increase membrane fluidity? A. a lower temperature B. a greater proportion of saturated phospholipids C. a relatively high protein content in the membrane D. a greater proportion of unsaturated phospholipidsWhich of the following factors would tend to increase membrane fluidity? A) a greater proportion of unsaturated phospholipids B) a greater proportion of saturated phospholipids C) a lower temperature D) a relatively high protein content in the membraneWhich of the following factors would tend to increase membrane fluidity? A) a greater proportion of unsaturated phospholipids B) a greater proportion of saturated phospholipids C) a lower temperature D) a relatively high protein content in the membrane E)The length of the fatty acid tail impacts the fluidity of the membrane. This is because the intermolecular interactions between the phospholipid tails add rigidity to the membrane. As a result, the longer the phospholipid tails, the more interactions between the tails are possible and the less fluid the membrane will be. 2.Which of the following factors would tend to increase membrane fluidity? A greater proportion of unsaturated phospholipids A relatively high protein content in the membrane A greater proportion of saturated phospholipids A lower temperature
