Causing the release of Ca⁺⁺

Dissociating into three parts

Dissociating into two parts

Binding to GTP

Causes the depolarization of the target cell

Is the receptor that can bind to the DNA

Is the receptor for gas molecules

Has a central water-filled pore for the movement of ions

G protein coupled receptor

Allows rapid responses in the cell

The presence of transmitter production machinery in the terminal

The production of vesicles in the terminal membrane

The use of Neurexin and Neuroligin to hold the vesicles in place

The need for Ca⁺⁺ for fusion of SNARE proteins in the vesicle and terminal membranes

The presence of destructive enzymes in the synaptic cleft

Includes reuptake mechanisms which is possible at all chemical synapses

Uses three different mechanisms not all of which are available at all chemical synapses

Controls voltage-gated Ca⁺⁺ channels to reduce the amount of transmitter releated

Use pre-synaptic inhibition at all synapses to reduce the amount of transmitter releated

Uses two different mechanisms both of which are available at all chemical synapses

Is an integral transmembrane protein with 7 trans-membrane segments

Is a membrane-associated protein with 7 trans-membrane segments

Is an ionotropic receptor protein

Is also used in cell-to-cell recognition processes

Is part of the MHC that is used to prevent auto-immune destruction
