What would happen to sequential action potentials along an axon if the
sodium potassium ATPase proteins of the neurone were non-functional?
a) Sequential action potentials would be possible, but they would
not result in the release of neurotransmitter from the presynaptic neurone
b) The first action potential would be possible, however
subsequent ones would not as the resting membrane
potential could not be restored
c) Multiple action potentials would be possible, however,
saltatory conduction would not occur slowing the action
potential’s conduction velocity
d) Multiple action potentials would be possible, but they would
travel backwards as well as forwards along the axon
e) No action potentials would be possible as the sodium and
potassium ions could not move across the membrane at all
