D)nucleotides.
E)sodium and potassium ions.

Question

Quizplus · Accepted Answer

The plasma membrane is primarily composed of a phospholipid bilayer, which means it is made up of two layers of lipid molecules. However, proteins are also embedded within the membrane, serving various functions such as allowing for the transport of molecules across the membrane or facilitating cell-to-cell communication. Carbohydrates may also be found on the outer surface of the membrane, where they play a role in cell recognition and signaling. Polymers and nucleotides are not typically found within the plasma membrane. Sodium and potassium ions may cross the membrane, but they are not embedded within it. Therefore, the best answer choice is A: proteins.
