WebAll cells contain ion pumps that use the energy at ATP hydrolysis to pump ions across the plasma membrane. These pumps create an electrochemical gradient across plasma membrane, including some transport processes In animal cells, the main ion pump is the sodium potassium pump. Complete the diagram below using the following steps. 1. WebMar 25, 2024 · The sodium-potassium pump uses the energy stored in ATP to pump sodium and potassium across the membrane. The resting membrane is established and maintained because the phospholipid bilayer contains a middle section that repels charged molecules and ions. As a result, the ions can only pass through the membrane if there are channels … WebFunctions and interactions with other nutrients Maintenance of membrane potential • A cell's membrane potential is maintained by ion pumps in the cell membrane, especially the Na + /K +-ATPase pumps. These pumps use ATP (energy) to pump sodium out of the cell in exchange for potassium. red blood cell diseases
