Electrogenic pumps biology
WebWhile you buildup electrochemical gradient, active transport happens. Once the cell uses an electrochemical gradient as the driving force for the sodium pump, not all gradient is 'used'. And what is most important, both processes happen simultaneously. There must be some friction in the system.

WebNov 1, 1992 · Two electrogenic proton pumps driven by ATP and pyrophosphate (PP 1) generate the ΔpH and Δ ψ for the secondary transport of other solutes into the vacuole. SV, slow vacuolar channel; FV, fast vacuolar channel. See text for discussion. ... Journal of Experimental Biology launched in 1923 as The British Journal of Experimental Biology. WebRather, this pump is electrogenic. Because the H + pump is driven by the hydrolysis of ATP, which provides a substantial amount of energy, it is capable of generating a large H + gradient across the cell membrane. For example, if the voltage across the membrane were zero, then the H + pump could establish a pH difference of about three pH units.
WebSep 30, 2024 · Electrogenic pumps are used to travel molecules in and out of a cell by establishing a concentration gradient. Hence, the statement that best describes the property of electrogenic pumps is B. Other options, like option A is correct but it does not describe the general property of the electrogenic pump.Option C is incorrect because not a large ... WebThe sodium-potassium pump is responsible for maintaining proper Na+ and K+ contents in living cells as well as creating a voltage across the cell membrane in animal cells. Electrogenic pumps are pumps like this that are involved in the establishment and maintenance of membrane voltages.

Here we show that this effect is not unique to halorhodopsin, but is also seen with activation of another electrogenic ion pump, archaerhodopsin.
