Web17 uur geleden · We recently reported that strong activation of the optogenetic chloride pump, Halorhodopsin leads to a secondary redistribution of K+ ions into the cell, through tonically open, leak K+ channels. Here we show that this effect is not unique to halorhodopsin, but is also seen with activation of another electrogenic ion pump, …
Due to the electrostatic and chemical properties, K + ions are larger than Na + ions, and ion channels and pumps in cell membranes can differentiate between the two ions, actively pumping or passively passing one of the two ions while blocking the other. hormone secretion and action; vascular tone; … Meer weergeven Potassium is the chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19.
