Which of the following statements is wrong with regard to the ionic contents of body fluids?

A. The dominant cation in blood serum is CO2.

B. The dominant anion in blood serum is HCO3-.

C.The dominant anions in the cytosol are the phosphates, e.g. H2PO4- and HPO42-.

D.  The dominant cation is the cytosol is K+

A. The dominant cation in blood serum is CO2.

B. The dominant anion in blood serum is HCO3-.

C.The dominant anions in the cytosol are the phosphates, e.g. H2PO4- and HPO42-.

D.  The dominant cation is the cytosol is K+

Explanation / Answer

* Option A is wrong statement with regard to the ionic contents of body fluids.. This is because CO2 is not a cation. It has a neutral charge, so it can't be Cation in blood serum( in general Na+,K+, Ca+2,Mg+2 are the common cations). Whereas the remaining options are correct statements with respect to blood serum and cytosol.
