Q. Both in cells and extracellular fluids diabasic phosphate (HPO4) and monobasic phosphate (H2PO-4) act as acid base buffers to maintain

Solution:

Phosphate Buffer System has 2 main components:
• Sodium salts of dihydrogen phosphate (H2PO4¯), a weak acid
• Monohydrogen phosphate (HPO42¯), a weak base
This system is an effective acid base buffer to maintain H+ concentration of cellular fluid
