Web16 May 2001 · It was assumed according to the Donnan interpretation that the measurable potential is produced by the transfer of the primary ion through the membrane. Since the 1960s, the author and co-workers have been investigating the problem of what can be the reason for the potential response of the electrodes. WebPotassium Permanganate (KMnO 4) is an inorganic chemical compound. It is also known as Condy’s crystals or permanganate of potash. A German-Dutch chemist Johann Rudolf Glauber was the first to discover the production of KMnO 4 in the year 1659. This compound is water-soluble and consists of two ions: Permanganate ion and potassium ion.

It contains a single class of gate consisting of 4 individual activation gates (the n -gates ), which respond more slowly than the activation gates of the Na channel. Thus if the membrane is depolarised, the n-gates open (slowly), and the K channel opens. i am not that old fnf
