resting potential is...
3 Na, 2 K
how many Na & K go through the pump at a time?
both channels closed
during resting potential, what channels are closed/open?
Na channel open, K channel closed
during depolarization, what channels are closed/open?
K channel open, Na channel closed
during depolarization/hyperpolarization, what channels are closed/open?
both channels closed
during return to resting, what channels are closed/open?
positiveduring resting potential, is the outside negative or positive?negativeduring depolarization, is the outside negative or positive?positiveduring hyper polarization, is the outside negative or positive?positiveduring return to resting, is the outside negative or positive?because the outside is negativewhy is the resting potential -70mv?because more Na is going through causing it to be more positivewhy is the depolarization graph increasing?because it took out more K than neededwhy is hyperpolarization negative?The refractory period is when what is happening?The membrane's potential is too low and it cannot fire again. Too many K+ have leftDuring resting state, which positive ion is in large quantities OUTSIDE the cell?Na+During resting state, which positive ion is in large quantities INSIDE the cell?K+
