The basic structure of the cell membrane of a neuron consists of a double layer of phospholipid molecules in which are embedded _____.
A) proteins
B) neurotransmitters
C) chromosomes
D) ions

Question

Quizplus · Accepted Answer

The double layer of phospholipid molecules in the cell membrane of a neuron contains embedded proteins, which play important roles in the function of the membrane. These proteins include ion channels, transporters, receptors, and enzymes. While ions also play a role in cell membrane function, they are not embedded in the phospholipid layer, but rather move in and out of the cell through ion channels and other protein transporters. Neurotransmitters are not typically embedded in the membrane, but rather are released into the synapse to signal to other neurons. Chromosomes are not part of the cell membrane structure.
