A pump exchanges it for potassium in parietal cells following gastrin binding.
DCCD and oligomycin directly block the diffusion of this ion. Tubulovesicular fusion to canaliculi permits efflux of this ion through a protein targeted by omeprazole, which belongs to a namesake class of drugs used to treat Zollinger–Ellison syndrome. This ion flows through UCP-1 after it is opened by thermogenin, an uncoupler found in brown fat. A pump exchanges it for potassium in parietal cells following gastrin binding. The Q cycle of complex III results in transfer of four of this ion to the intermembrane space, which helps establish the gradient that drives ATP synthesis. For 10 points, name this cation (CAT-ion) that consists of a single subatomic particle, an ion donated by Brønsted acids.
