What is the difference between the 2 conformational states. The sudden shift from a resting to an active state, when the neuron generates a nerve impulse, is caused by a sudden movement of ions across the membrane—specifically, a flux of Na + into the cell. Sodium potassium pump Carrier protein involved in active transport in animal cells. d. sodium and potassium ions into the cell. That must make the outside more positive than the inside, and that actually is true. Na⁺/K⁺-ATPase (sodium–potassium adenosine triphosphatase, also known as the Na⁺/K⁺ pump or sodium–potassium pump) is an enzyme (an electrogenic transmembrane ATPase) found in the membrane of all animal cells. The concentration of potassium ions should be … D) ionizes sodium and potassium atoms. This pump is powered by ATP.
