Inhibition of the proton pump in the parietal cells has been established as the main therapeutic principle in the treatment of acid-related diseases, such as peptic ulcer and gastro-oesophageal reflux. The proton pump inhi bitors are tailored for their purpose. They accumulate in the target...
Recently, a number of closely related H+/K+-ATPase isoforms have been discovered. These isoforms are present in organs other than the stomach, including the colon and kidney, where they contribute to acidbase and potassium homeostasis. The structure, expression and physiological roles of the ...

thaliana cell culture protoplasts that expressed a YFP-fusion of the V-PPase. In plants, two types of V-PPases have been identified, which differ in their sensitivity to potassium: K+-stimulated (Type I) and K+-insensitive V-PPases (Type II) can be distinguished (Belogurov and Lahti, ...
In addition, the activities of other ion channels, including calcium, sodium, and potassium channels and glutamate and GABA receptors, are modulated by extracellular proton concentration. For instance, GluK2/K4 kainate receptors are potentiated by protons (Fig. 4a, top)38. In this regard, we ...
Additionally, the decrease of the dielectric constant of the membrane is expected to enhance the sensitivity of the corresponding CHEMFET to potassium ions, according to equation 2. The theoretically expected effect of the plasticizer dielectric constant on the Potentiometric response of the K-CHEMFET...
What is the charge of potassium? What are protons, electrons, and neutrons? If the charge on the atom is 0, what does this mean? How many electrons would it take to equal the mass of a proton? What is the charge on the barium ion?

What is the number of electrons in a Ni2+ ion? 25. Compute the number of electrons in a P3− ion. 26. Give the number of electrons in silicon (Si) atom. 27. How many electrons are there in a F− ion? 28. Find the number of electrons in a potassium ...
In the chemical elements of atomic number 17 to 19, for example, the chloride ion (Cl−), the argon atom (Ar), and the potassium ion (K+) have 18 electrons in closed-shell configurations and are chemically quite stable. The number of electrons present in the neutral atoms constituting ...
