Ion concentration Flashcards
where is sodium more concentrated
outside the neuron
where is potassium more concentrated
inside the neuron
where is calcium more concentrated
outside the neuron
where is chloride more concentrated
outside the neuron
why does calcium need to be more concen on the outside
signals the binding of vesicles and release of NTs
in an AP where does Na+ flow
into the cell
in an AP where does K+ flow
out of the cell
Na+ flow during an AP makes the inside of the cell more + or -
more positive (depolarisation)
K+ flow through leak channels during an AP makes the inside of the cell more + or -
more negative (repolarisation)
what ion(s) is this nernst equation for
E = 58log ([X]ecf / [X]cyto)
Na+ and K+
what ion(s) is this nernst equation for
E = 58log ([X]cyto / [X]ecf)
Cl-
what ion(s) is this nernst equation for
E = 29log ([X]ecf / [X]cyto)
Ca2+
