Question

The function of "Sodium pump" is a biological process operating in each and every cell of all animals. Which of the following biologically important ions is also a constituent of the pump?

• A. $\ce{K^+ } $
• B. $\ce{Fe^{2+} } $
• C. $\ce{ Ca^{2+}} $
• D. $\ce{ Mg^{2+}} $

Answer 1

The Correct Option is A

The function of "sodium pump" is a biological process operating in each and every cell of all animals. $K ^{+}$ion, a biologically important ions is also a constituent of this pump. $Na ^{+}$is a major cation present in blood plasma (outside cells). $K ^{+}$is major cation present in cytoplasm (inside the cells). Higher concentration of $K ^{+}$and lower concentration of $Na ^{+}$ion is present inside cell and tissue. Lower concentration of $K ^{+}$and higher concentration of $Na ^{+}$ion is present in fluid, bathing cells and tissues (blood plasma).
