Web8 feb. 2024 · 3 minutes. Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell. Thanks to these pumps, their unicellular owners can adjust to the environment’s pH value or salinity. WebSodium-Potassium ATPase Pump. Under resting conditions, Na + slowly leaks into the cells and K + leaks out of the cell because of electrochemical driving forces. Whenever an action potential is generated, additional Na + enters the cell and K + leaves the cell. While the number of ions moving across the sarcolemmal membrane in a single action ...
