It involves an enzyme referred to as Na + /K +-ATPase.This process is responsible for maintaining the large excessof Na + outside the cell and the large excess of K + ions on the inside. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. The sodium-potassium pump, also called Na, K-ATPase, is responsible for active transportation. The sodium potassium pump (NaK pump) is vital to numerous bodily processes, such as nerve cell signaling, heart contractions, and kidney functions. The process basically consists of the following steps. Sodium-Potassium Pump Explained. The sodium-potassium pump can be quite a perplexing topic especially to nursing students due to its nature, function, and how the entire process contributes to healthier well-being. Below are the steps that the sodium-potassium pump uses to function: Three sodium ions form inside the cell bind to the pump. Sodium potassium pump is the process of moving sodium and potassium ions across the cell membrane in an active transport process involving the hydrolysis of ATP to provide the necessary energy. How a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. Typically, I’d show my students a video or two, talk about the sodium potassium pump a bit, and call it a day. At that point, two potassium ions from outside the cell bind to the protein pump. This Biology video tutorial explains how the sodium potassium pump works inside the cell membrane. The potassium ions are then transported into the cell, and the process repeats. Start studying Sodium Potassium Pump Steps. The Phosphate group form a molecule of ATP binds to the pump. The process of moving sodium and potassium ions across the cell membrance is an active transport process involving the hydrolysis of ATP to provide the necessary energy. In doing so, it pumps the three sodium ions out of the cell. Sodium Potassium Pump Summary Steps involved in the Sodium-Potassium Pump the sodium The sodium-potassium pump is found in the plasma membrane of almost every human cell and is common to all cellular life. The pump is powered by a molecule of ATP. In more detail: Sodium ions bind to the pump and a phosphate group from ATP attaches to the pump, causing it to change its shape. This procedure demands energy to transfer the sodium and also potassium ions into and away from the cellular materials. 3 Na+ ions from the ICF bind to the pump (with ATP or adenosine triphosphate attached). Sodium-potassium pump (or Na+/K+ -ATPase) are transmembrane proteins that actively transports Na+ ions to the extracellar fluid (ECF) and K+ ions to the intracellular fluid (ICF). The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. At this very moment, there is a diversified network of nerve impulses running throughout the human anatomy. This pump is powered by ATP. These ions travel against the concentration gradient, so this process requires ATP. The sodium potassium pump in particular needs to be presented in such a way that shows how it changes its shape and that it pumps 3 Na+ out and 2 K+ inside. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in. The ATP allows the shape of the pump to change, emptying its contents either into or out of the cell.
