<span>Epithelial cells in the stomach require the use of coupled transport to make gastric acid. They use hydrogen potassium ATPase, which is an electroneutral pump, and exchanges potassium for hydronium in order to produce the gastric acid.</span>
Because in that way we keep thinking about them. How can you forget something when you're thinking about it?!
It totally depends upon whether modification is being done in somatic cells or germ cells. Somatic cells modification is ethically accepted because it doesn't pass from one generation to another generation but germline modification is considered as unethical because the modification will pass on to the next generation leading to the persistence of modification in future generations. The problem with genetic modifications is that the impacts of modifications are unpredictable, rather than being fruitful they may lead to lethal mutations so if it occurs in just somatic cells, then even if it is lethal/harmful, it will be confined to only that individual but if a lethal mutation occurs in germ cells then it will pass on to the subsequent generations and it will persist in all future generations.
