Witryna4. Two potassium ions (2 K+, shown as blue triangles) from outside the cell bind to “lock and key sites” on the protein of the Na+-K+ pump. 5. The protein of the Na+-K+ … WitrynaThe sodium-potassium pump, which maintains electrochemical gradients across the membranes of nerve cells in animals, is an example of primary active transport. The formation of H + gradients by secondary active transport (co-transport) is important in cellular respiration and photosynthesis and moving glucose into cells.

Witryna11 sty 2024 · The Sodium-Potassium Pump Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. To move these molecules against their concentration gradient, a carrier protein is needed. WitrynaHow a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump goes through cycles of shape … marriott downtown philadelphia parking rate
