Transpo of sodium potassium is called as
**Core Concept**
The transport of sodium and potassium across cell membranes is a crucial process in maintaining cellular homeostasis and regulating the resting membrane potential. This process involves the coordinated action of various ion channels and pumps that facilitate the movement of these ions in and out of the cell.
**Why the Correct Answer is Right**
The correct answer refers to the sodium-potassium pump (Na+/K+ ATPase), which is an enzyme that actively transports sodium ions out of the cell and potassium ions into the cell, using the energy from ATP hydrolysis. This pump is essential for maintaining the electrochemical gradient across the cell membrane, which is necessary for proper neuronal function, muscle contraction, and other cellular processes. The sodium-potassium pump is a type of P-type ATPase, which is a family of enzymes that use the energy from ATP hydrolysis to transport ions across cell membranes.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the transport of sodium and potassium ions. The sodium-potassium pump is a specific type of transporter that is responsible for this process.
**Option B:** This option is incorrect because it refers to the sodium-calcium exchanger, which is a different type of transporter that exchanges sodium ions for calcium ions across the cell membrane.
**Option C:** This option is incorrect because it refers to the sodium-potassium-chloride cotransporter, which is a type of transporter that cotransports sodium, potassium, and chloride ions across the cell membrane.
**Clinical Pearl / High-Yield Fact**
The sodium-potassium pump is an essential enzyme that is sensitive to digitalis toxicity. Inhibition of the sodium-potassium pump by digitalis glycosides can lead to an accumulation of sodium ions in the cell, which can cause cardiac arrhythmias and other cardiac complications.
**Correct Answer:** C. Sodium-potassium-chloride cotransporter is not the correct answer, however, based on the provided options and explanation, the correct answer is not explicitly mentioned. For the sake of completion, the correct answer should be the one that matches the description provided in the explanation.
