What are the three important functions of the lipid bilayer of the plasma membrane
A)forms the basic membrane structure; hydrophilic interior acts as barrier; aids in RNA transfer
B)forms the basic membrane structure; hydrophobic interior acts as barrier; responsible for fluidity
C)forms the basic membrane structure; hydrophobic interior acts as barrier; aids in RNA transfer
D)allows electrical flow via nerves; hydrophobic interior acts as barrier; responsible for fluidity

Question

Quizplus · Accepted Answer

The lipid bilayer of the plasma membrane has three important functions: forming the basic structure of the membrane, creating a hydrophobic barrier that separates the inside and outside of the cell, and contributing to the fluidity of the membrane. Choice B correctly identifies all three functions. Choice A is incorrect because the hydrophilic interior of the membrane does not act as a barrier - it is actually the hydrophobic interior that provides the barrier function. Choice C is incorrect because the membrane does not generally aid in RNA transfer. Choice D is incorrect because the lipid bilayer does not directly allow for electrical flow via nerves.
