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, … WebIon channels enable specific ions fitting into the channel to move down their concentration gradient via passive transport, to equalize the concentrations on both sides of the cell membrane. On the contrary, ion pumps implement active transport by driving ions against their concentration gradient by using energy sources such as ATP.
