Equilibrium Potentials and Driving Force
HTML-код
- Опубликовано: 27 окт 2014
- Ions move in response to concentration gradients and voltage gradients... but when the ions move, the gradients change! WHY do they move? Do they ever reach an equilibrium? Do you really need physics to understand this? Not really - although I throw it in at the end! Don't worry - it's the Nernst Equation, Penguin Prof Style!

the topic was so confusing while reading the book but now it seems pretty easy
thanks for such an incredible explanation
Thank you for explaining! Its so sad that our education system can't slow down to explain these concepts, rather it wants us to memorize everything.
Best video ever for explaining these concepts, super helpful, love everything about it!!
Hello,
I'm a French student in Neuroscience and I just want to thank you so much for this amazing video which made me understand those two points very easily and quickly.
What do you is amazing :)
I love the first half of your original video and how you use the human experience. I thought, about you doing a future video or podcast translating your knowledge as it relates to to all areas of the every experience of the human condition.Just throwing out an Idea.

Really great video, the analogy was awesome. LOVED IT!!!
great explanation thank you
Ficando loucão com esse vídeo!!!
Amazing. I was stuck in these details for hours..
Thank you for this explanation
i love your voice , u explained the concept very well , thank u
Very useful, Thanks!
I'm having a eureka moment! Thanks for this exceptional explanation.
I love being a part of those moments!!! You are so welcome.
Thank you for this analogy. I'm in my second year of med-school and this is analogy was beautiful.
Oh that's really helpful ! thank you so much !!
Very nice
Wow..what a explaination!..thank you
You are welcome!
so so helpful!! thanks so much
Glad it was helpful!
Are you still making videos? For me, these are brilliant. What a great teacher!
Yes I am! I've got a new job this year, serving as the Teaching with Technology Coordinator for my college, so I've had to focus on EDU content, but there's more BIO on the way!
Very helpful. This video really cleared my concepts.
I'm so glad to hear that! Thanks for watching.
Thank you!!
You're welcome! Thanks for watching!
This was so incredibly helpful! Thank you! Subscribed :)
Awesome! Thank you!
Do you happen to have a video showing how to actually do the Nernst equation from start to finish?
great explanation! thank you
Glad it was helpful!
I really love this !!!!! Thanks 🙏🏻 liked and subscribed ❤️
Yay! Thank you!
God I can’t say how this was useful and English is not even my first language! That was so clear and well explain!
Chapeau !
Thank you so very much!!!
This helped :)
The definitions are starting to get more clear.
omg thank you so much it's a few days I been struggling with this and you made me understand it
OMG you are SO welcome!!!
thank you!
You're welcome!
Would you say that an Ion's conductance would be greatest when its Eq potential equals the Membrane Potential?
You are super!
I've learned more watching your videos in the last 20 minutes than 6 weeks of attending Neurobiology lecture. I wish you had more videos on the neurons and cell biology. Thank you so much!!!
So happy to hear you've found the videos helpful.... I'm working on more nervous system stuff right now! :)
Thank you so much for the lesson, but I have a question that you might have help me with finding an answer to.
What if we, humans, were wrong? with all the numbers and all the formulas. I know that might seem a little stupid, but i really have been thinking a lot about a lot of things that happen in our universe. What if we've found something much faster than light? that's one things I have been dreaming of. We have based our learning on numbers, constants and theories. I think we need to work harder. who knows, we might someday harness power from other stars, or apply the first Warp Drive. Thanks again, and by the way your teaching analogy is perfect. Keep up....
Thanks
THANK YOU SO MUCH FOR THE COFFEE!! Much appreciated!
@@Penguinprof you’re more than welcome!
I think it's the brain that determines the driving force based on a person's beliefs and only a change in beliefs can change it, either individually or collectively. I also believe that consciousness is demonstrated by it's ability to change the condition and position of any particle from its otherwise inevitable position and the inevitable position of any particle is also determined by conscious intention. There is no difference between the laws that govern the interactions of people, atoms, events, or anything, because everything is made of pure imagination. Ironically, that's why a good deed shines so in a weary world. Know what I mean?
you're amazing
Thank you!!!
Brutal! que video fantástico, continuem!! Força e parabéns pelo excelente trabalho! Desculpem o meu inglês :/
whatttttt???
thank you, im a msc student doing neuroscience and biochemistry and have a question, no one ever really explains why we must use logarithmic form, im assuming this calculation is based onlogarithmic transformation, and have been told this info does not exist because in the olden days researchers never had calcultors, eg the work by kessel on the k+ of frog,leech so theefor it was compulsory to know logs and why we use them. My lecturer has said that we won tunderstand them because of calculatorsand lack of communication with high school. So why do we use logarithmic transformation with the nernst equation for membrane potentials, reversal potentials and how does it relate to why graphically in K+ decade change is -60mvs?
Now I can only understand this in terms of happy points :3
You are so funny, so sweet and so efficient. I got to understand everything so fast. I love your energy and thank you so for sharing. I hope one day I'll be a neuroscientist. Would that be too late starting at 47 and no science background 😁 .. Doesn't matter I am doing it by passion. Xx
Thank you so much! No, it's never too late to follow your dreams. ALL the best of luck to you!!
I like your voice.
Penguin blushing! Thanks!
why does the Eion of Cl- have a negative value in the table (~9:30) but comes out as a positive value when you use the Nernst equation to calculate it?
This is impossible to answer in a text box - but check out Equation 11 here: www.physiologyweb.com/lecture_notes/resting_membrane_potential/resting_membrane_potential_nernst_equilibrium_potential.html
@@Penguinprof Right! I forgot about charge. Thank you, this makes sense! : )
Alguém aqui?
☝️facts no cap
3;57 i guess it's inside/outside not outside/inside
Hey, I think driving force is actually the membrane potential - Eion
hey, that's right :)
Vi o vídeo 100 vezes, so para aumentar as vossas views ;) De nada!!!
