What is the resting membrane potential? The cell's resting membrane potential is the electric potential of the cell, and exists as a result of ions moving into and out of the cell. This video covers the definition of resting membrane potential, as well as how to calculate it using the Nernst equation. Find our full video library only on Osmosis: osms.it/more.

osmosis! this video is brilliant !! I've read about this topic from endless sources but I've never felt until now that I've truly grasped the concept. Thank you so much for your work.

@MrBeachwaves 4 года назад

Thanks for another great video! Would have preferred a more conceptual rather than a mathematical explanation though, as well as an explanation of the role of the NaKATP pump and its contribution to the resting membrane potential.

@dannichols6261 4 года назад

Yes, I agree, it's not so good to just *mention* the Na/K pump, and then say nothing *about* it! I think it simplifies to: the Na/K pump helps maintain the *concentration gradient* , while the *leak channels*, in relation to *both* the concentration gradient *and* the (sort-of opposing) electrostatic gradient, are what balance out to yield the resting membrane potential.

@MrTote191 7 лет назад

Could you explain what's the role of the Na K pump in calculating the resting membrane potential?

@dannichols6261 4 года назад

Yeah, they *don't* explain that at all. They do present some interesting information (ie, ion concentration values). They *mention* the Na K pump, but do *not* explain its role in maintaining membrane potential. Not good! And while they *mention* an 'inward rectifier channel', they don't *explain it* at all!

@magranin7319 2 года назад

@@dannichols6261 It would be great if they did but I think this video is targeted at people who already have a good understanding of passive and active transport systems. RU-vid is great, there are a lot of videos that cover that in depth. I would watch them and go back to this one. Hope this helps :)

@spectroxis6418 8 месяцев назад

One thing I’d like to add to this is permeability. At rest without any voltage propagating(action potential) the cell is very permeable to potassium so the summation of these will decrease the effect of calcium, sodium, and chloride a lot and only affect the potassium slightly. GHK equation

@anne-sophiepattijn8302 Год назад

When calculating the membrane potential for when the membrane is permeable to multiple ions, why is it that when I do the Goldman equation using the information in your video I get -83mV rather than what you got which was -86mV? I did this: Vm = -61.5 x log( ((150 x 0.9) + (10 x 0.01) + (0.001 x 0.01) + (103 x 0.08)) / ((5 x 0.9) + (142 x 0.01) + (5 x 0.01) + (4 x 0.08)) ) = -83mV
