Q: Given a passage and a query based on the passage, generate an unambiguous, concise and simple answer to the query from information in the passage. Note that the answer may not be present in exact form.
Function. The Na + /Ca 2+ exchanger does not bind very tightly to Ca 2+ (has a low affinity), but it can transport the ions rapidly (has a high capacity), transporting up to five thousand Ca 2+ ions per second. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. Passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy. What functions do carrier proteins perform in active transport? Carrier proteins allow molecule to bind to them; they change their shape to transport material across the cell membrane. The sodium-potassium pump is integral in maintaining the acid-base balance as well as in healthy kidney function. Energy is derived from pumping sodium outside the cell, where it becomes concentrated, wanting to push its way back in. This energy is used to remove acid from the body. The sodium-potassium pump also functions to maintain the electrical charge within the cell. This is particularly important to muscle and nerve cells. During nerve transmission and muscle contraction, potassium exits the cell and sodium enters, resulting in a change in electrical charge that causes a nerve impulse or muscle contraction. A: The sodium-potassium pump is an essential cellular membrane protein that functions by pumping out three sodium ions and taking in two potassium ions. This mechanism preserves the electrochemical gradient formed from the varying concentrations of sodium and potassium ions within the cell and its exterior. Continue Reading When an enzyme in the pump, called sodium-potassium-ATPase, splits the phosphate from the ADP, the energy released powers the transport action of the pump. Passive transport: membrane channels. The sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na + and K + at constant Sodium-potassium pump is pivotal to body's function. The story of the sodium-potassium pump has strong ties to Denmark. In 1997, the Danish scientist Jens Chr. Skou received the Nobel Prize in Chemistry for his discovery, and over the years, research on the pump has remained a strong focus area at Aarhus University. Listed below are several cellular and pharmaceutical conditions in which this happens. 1 The internal [Na+] is higher than usual (like it is when digitalis glycoside medications block the Na+/K+ -ATPase pump.) 2 The Sarcoplasmic Reticulum release of Ca2+ is inhibited. 3 Other Ca2+ influx channels are inhibited. The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in. 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 this new shape, the pump releases the three sodium ions and now binds two potassium ions. Once the potassium ions are bound to the pump, the phosphate group detaches. The sodium-potassium pump is a P-type ATPase sharing similarities with other P-type ATPases, notably the calcium-ATPase in the sarcoplasmic reticulum and the hydrogen-potassium ATPase in gastric cells (2). Quick Answer. The sodium-potassium pump is an essential cellular membrane protein that functions by pumping out three sodium ions and taking in two potassium ions. This mechanism preserves the electrochemical gradient formed from the varying concentrations of sodium and potassium ions within the cell and its exterior.
