my prof uses donna equilibrium to explain why the inside of the cells is negatively charged, while showing each compartment in electrical neutrality. so i was pretty confused, so does a lot of videos on yt. can you explain why they're using that example? like the only thing i got from that is, one of the compartment has higher oncotic pressure.
To answer your question, we first need to understand *electrochemical* & then *gradient* . 1. Electro-chemical refers to a volume of space containing *ions* of *chemicals* . Chemicals are atoms of elements, or molecular combinations of elements. Ions are parts of chemicals which have lost or gained electrons, thus conferring a *charge* to them. 2. A *gradient* is a differential distribution of any substance (more of a substance in one place and less in another). 3. To move *down* a gradient is to move *from* a place of high concentration, *to* a place of lesser concentration. 4. To specifically move down a *chemical* gradient, is to move from a place of more concentration of a *chemical substance* to a place of less of that chemical substance, by diffusion (because at anything other than absolute zero, all molecules are in kinetic motion, either bouncing off one another, or at least just 'vibrating'). 5. Alternatively, to move down an *electrical* gradient is to move from a place of *high charge* to a place of *lesser* charge, by repulsion of like charges. 6. So moving down an *electrochemical* gradient is a *combination* of the two, such that *chemicals* will move to attempt to equalize the concentrations of those chemicals within a space, but any imbalance of *charges* caused by that movement will force some of the charged ions *back* against the *chemical* gradient. 7. The result would be a *balance* between the molecules' attempts to equalize the chemical concentration, and the forces of the electrical charges. 8. A better explanation might be: en.wikipedia.org/wiki/Electrochemical_gradient
Finally someone who explain the details and why everything is happening, thank you
First video I've seen that explains equilibrium potential, thank God
Thank you for the lesson Dr.
As a psychology student that study’s neuropsychology, this helps a lot. Thanks!
Literally the only video I understood what was happening. Good articulation.
The best explanation I've ever seen.
Awesome ...i am a medicine student ..and you answer all my questions by this video ..🌸🌸
Excellent vid, exactly what I have been looking for, thank you 🙂
Best video i have watched till now pretty simple!
Glad it helped!
I am a molecular biology student and thanks for this conceptual video about electrochemical gradient
Awesome. Im a medicine student. Thankyou very much
Why is the concentration of K+ lower intracellularly than extracellularly here? I thought K+ was higher inside cells?
C’était parfait!!!
WOO thank you very much for the explanation
i wish i can give you an award
You explained this very well. Thank you
Perfect.
With which software you draw a move this item?
Videoscribe originally. Now After Effects.
You are amazing thank you!
Hi, nice video. May I use it for teaching? (I would need to add Spanish translation) Thanks!
Yes, please do!
Just what i was looking for, thank you.
Thank you Dr Mason
absolutely helpful, wish I could give it more than 1 like!
animation is great so is the explaning. Thanks!
Thanks!!! :) man,you really helped.
Is there an explanation in spanish?
Thank you so much
Amazing !!!

Thank you so much for your help! :)
You're welcome!
Thanks 💎
thanks a lot it was so helpful to me
Thanks😍
thanks so much ^^
thannks a lot...
Pierce Morgan, is that you?
