Identify the true statement(s) about the plasma membrane.
A)Its lipid region allows most ions to diffuse between the cytosol and ECF.
B)Its channels allow cholesterol to diffuse between the ECF and cytosol.
C)Some of its carriers transport sodium.
D)Its phospholipids are held to one another by CAMs.
E)All except its phospholipids are held to one another by CAMs.

Question

Quizplus · Accepted Answer

Some carriers in the plasma membrane transport ions such as sodium. The other statements are not true. A is incorrect because the plasma membrane is selectively permeable and only allows certain ions to diffuse. B is incorrect because cholesterol is not transported across the plasma membrane. D is incorrect because phospholipids are held together by hydrophobic interactions, not CAMs. E is incorrect because CAMs are only involved in holding some proteins together within the plasma membrane, not the entire membrane itself.
