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 potassium ions are then transported into the cell, and the process repeats. The process basically consists of the following steps. 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. This pump is powered by ATP. The sodium-potassium pump, also called Na, K-ATPase, is responsible for active transportation. Typically, I’d show my students a video or two, talk about the sodium potassium pump a bit, and call it a day. Below are the steps that the sodium-potassium pump uses to function: Three sodium ions form inside the cell bind to the pump. How a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The Phosphate group form a molecule of ATP binds to the pump. The ATP allows the shape of the pump to change, emptying its contents either into or out of the cell. Start studying Sodium Potassium Pump Steps. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP. 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. The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. 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. 3 Na+ ions from the ICF bind to the pump (with ATP or adenosine triphosphate attached). For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in. The sodium potassium pump (NaK pump) is vital to numerous bodily processes, such as nerve cell signaling, heart contractions, and kidney functions. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. 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. Learn vocabulary, terms, and more with flashcards, games, and other study tools. At that point, two potassium ions from outside the cell bind to the protein pump. This procedure demands energy to transfer the sodium and also potassium ions into and away from the cellular materials. At this very moment, there is a diversified network of nerve impulses running throughout the human anatomy. Sodium-Potassium Pump Explained. 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. In doing so, it pumps the three sodium ions out of the cell. 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. 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.
