Both in cells and extracellular fluids diabasic phosphate (HPO 4 ) and monobasic phosphate (H 2 PO - 4 ) act as acid base buffers to maintain
Options
- AK + concentration of extracellular fluid
- BNa + concentration of extracellular fluid
- CNa + concentration of cellular fluid
- DH + concentration of cellular fluid
Correct answer
D. H + concentration of cellular fluid
Step-by-step solution
Phosphate Buffer System has 2 main components: • Sodium salts of dihydrogen phosphate (H2PO 4 ¯), a weak acid • Monohydrogen phosphate (HPO 4 2¯ ), a weak base This system is an effective acid base buffer to maintain H+ concentration of cellular fluid
