Question

Which of the following ions acts as a buffer to minimize changes in intracellular pH?

1) phosphate
2) bicarbonate
3) chloride
4) potassium
5) sodium

Answer 1

Phosphate ion acts as a buffer to minimize changes in intracellular pH.

Step-by-step explanation:

The ion that acts as a buffer to minimize changes in intracellular pH is

1. phosphate

Phosphates are found in the blood in two forms - sodium dihydrogen phosphate (NaH2PO4), which is a weak acid, and sodium monohydrogen phosphate (Na2HPO4), which is a weak base. These forms of phosphate can help maintain the pH balance within cells and prevent drastic changes in intracellular pH levels.
