What do excitatory NT bind to? - - ligand gated sodium channels and open them up If it reaches -55 then it will fire What do inhibitory NT bind to? - - potassium gated ion channel Potassium then leaves the cell taking its positive current with it and takes the voltage inside the cell further from threshold so that it will need a larger than normal stimulus because it is further away from threshold could also bind to chloride channels - chloride will move in which is negative Glutamate ...

G-Protien coupled receptors and how they interact with drugs - G-protein coupled receptors (GPCR) interact with drugs through 7 regions of proteins that span and innervate the cell membrane and trap the molecule into the receptor site like an interwoven basket (Insel & Sriram, 2018). Drugs can then enter this space and interact with the GRCP. A specific interaction and binding with a site on one or more of the regions of proteins within the GPCR, and drugs bound with the GRCP can stimulate t...
