Is a phospholipid molecule a nonpolar water insoluble head attached to a long polar soluble tail?
The answer is false.
Is this true or false a phospholipid molecule has a nonpolar water-insoluble head attached to a long polar soluble tail?
What is the effect of having the polar and nonpolar ends of phospholipid molecules oriented as they are in this illustration?
What compound composes most of the cell membrane and how is it suited to the function of the membrance?
The compound that composes most of the cell membrane in most animal cell is called...phospholipid. This molecule works by being amphipathic, it has a polar end and a nonpolar end. This allows two layers of this molecule to for the phospholipid bilayer, with the nonpolar tails excluded from the water and turned inward and the polar heads turned outward into the solution.
The structure of cell membrane allows nonpolar molecules to diffuse, but not polar molecules. Membrane architecture is in the form of a phospholipid bilayer. A single phospholipid has a "head" composed of a polar NH3 group, and two "tails" composed of nonpolar fatty acids. The lipids spontaneously arrange themselves into bilayers with the hydrophilic heads directed outward, and the hydrophobic tails facing inward. Because nonpolar solvents can only dissolve nonpolar solutes, polar molecules cannot mix…
