lecture 14 redone Flashcards
glutamate is a
excitatory neurotransmitter
glutamate binds to
AMPARs and NMDARs in the body
are NMDA receptors or AMPA receptors more sensitive
NMDA receptors
example of NMDA receptor
GluN
example of AMPA receptor
GluA
kainate receptors
GluK
ionotropic glutamate receptors are made up of _ subunits
4
AMPAR subunits are
GluA1-4
how does the flip variant affects the GluA channel
lengthens the time the channel is open for
if the GluA2 is present is makes the receptor impermeable to
calcium
what makes glua2 impermeable to calcium
glutamine (q) is swapped for argenine (r) which is positively charges repelling the calcium
NMDA receptors are ______ permeable
calcium
magnesium wedges itself into the pore, its drawn in due to the
negative field inside the membrane
as the cell is depolarised theres less of a negative feild so the magnesium
is forced out and the pore opens
NMDA receptors require the presense of
glutamate and require the cell to be depolarides to be open
