Sodium potassium pump steps
An Introduction to the Nervous System
Sodium Potassium Pump - an enzyme that transports . potassium ions into the cell while transporting sodium ions out the cell, both against their concentration . gradient, uses ATP. b. Endocytosis- The movement of substances into . the cell by a vesicle. c. Exocytosis-The movement of substances . out of a cell by a vesicle

1. The diagrams below represent the six steps in one cycle of the sodium-potassium pump. The order of the steps has been scrambled. Beginning with diagram d (numbered 1), sequence the remaining diagrams by writing the appropriate numeral in each blank. 2. On which side of the membrane are Na+ ions released from the pump? 3.

The sodium-potassium pump uses energy in the form of ATP to move these ions against their concentration gradients and establish the “normal” intracellular ion concentrations. Set the sodium-potassium pump so that it is open to the inside of the cell. Record the initial concentrations of Na+ and K+in the data table on your answer sheet.

Sodium-Potassium Pump. One of the most important membrane pumps in animal cells is a carrier protein called the sodium-potassium pump. In a complete cycle, the sodium-potassium pump transports three sodium ions, Na+, out of a cell and two potassium ions, K+, into the cell. The sodium-potassium pump has four steps: Three sodium ions inside the ...
