- The tails of the phospholipids of the plasma membrane are composed of _____ and are _____? a. phosphate groups; hydrophobic b. fatty acid groups; hydrophilic c. phosphate groups; hydrophilic d. fatty acid groups; hydrophobicwould substances be able to pass through the plasma membrane if the phospholipi tails of the plasma membrane were oth satueated fatty acids? why or why not, explain?Cholesterol is abundant in the plasma membrane. Would you expect cholesterol to flipbetween the two leaflets of the membrane faster than phospholipids, or slower, or atthe same rate?
- Why should triacylglycerol be insignificant component of plasma membrane ?A phospholipid bilayer with equal amounts of saturated and unsaturated fatty acids displays a specific permeability to glucose. What effect will increasing the proportion of unsaturated fatty acids in the bilayer have on the membrane's permeability to glucose?Why must cholesterol, although lipid-soluble, cross most membranes by means of receptor-mediated endocytosis or transporters? Propose a mechanism for co-transport of cholesterol through a plasma membrane
- The tails of the phospholipids of the plasma membrane are composed of ____ and are ______?"Although lipid molecules are free to diffuse in the plane of the bilayer, they cannot flip-flop across the bilayer unless enzyme catalysts called phospholipid translocators are present in the membrane", is true or false.Describe ONE modification that could happen to the phospholipids in a membrane that would increase the permeability of the membrane to small non-polar molecules such as oxygen gas. Explain why this modification would increase membrane permeability.
