@jim mcnamara Thank you for the reference.

Dear @Andy Resnick , Your answer could not be more straightforward. But I don't think I'm disputing in any way that the various intracellular concentrations do not remain constant. I therefore agree with the first sentence of your answer in a perfectly indisputable way. Concerning the second...

I totally agree with you and that is the purpose of my question. The theory seems to be in complete contradiction with logic and facts. The current theory imposes a constant outflow of potassium from the cell and a mechanism that could maintain a certain balance but only to a very small extent...

Thank you for this answer but the "no" seems... hasty. What is the mechanism you are referring to? The Na/K pump which is involved in only 5% of the membrane potential? Moreover the K gradient is unfavorable =>4/140 to any inward diffusion, isn't it?

Hello everyone, All living things have a growth cycle in which they gain mass and volume. These elements are obviously and undoubtedly taken from the environment in which these creatures live. Therefore, it is undeniable that the amount of potassium, for example, in the body increases during...

Thanks for the confirmation, Borek.

OK, It seems elementary: Chlorine on one side (positive electrode) and hydrogen on the negative electrode.

Hello, What are the oxidation-reduction reactions that are produced at the electrodes when they are considered inert (platinum or silver coated)? Let's take a simple example of a saline solution of KCl and apply a DC voltage between the two electrodes. Thank you in advance.

Hi, The picture comes from there https://en.wikipedia.org/wiki/Hodgkin%E2%80%93Huxley_model Normally the resistors (ion channels) which are symbolised here are connected between the external medium and the inside of the cell because they are enclosed in the membrane. The capacity, too. The...

Hi, Here is a basic picture of the famous electric circuit of the HH model. Can someone please tell me the anatomical locations of the connections marked in red in the cell? Thanks.

Thanks again Atyy, The same phenomenon applies to batteries. They have an internal EMF even if they are not connected but one can not know their inner potential without connecting them. The charge separation creates an Electric field also called an electroneutrality field. It is the force that...

Thanks for this reply.

The theory says it may exist but it not directly measurable. => from this book https://link.springer.com/book/10.1007/978-1-4613-4560-2

Well, the links you gave show electrodes then there is a RedOx reaction with charge transfer within the external circuit. That is not my question.
