Released glutamate traverses this space by passive diffusion, and because its target glutamate receptors in the postsynaptic neuron are heavily enriched in specialized membrane structures that are ...

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the ...

This does not require a supply of energy because diffusion is a spontaneous process. This occurs when molecules are moved across the cell membrane from an area where they are at a low ...
