The constant pH of body fluid is maintained by buffer salts like

A

Potassium phosphates

B

Sodium phosphates

C

Adenosine monophosphate

D

Sodium and potassium phosphates

Text Solution

Verified by Experts

The correct Answer is:
D
The phosphate buffer system is comprised of two ions: hydrogen phosphate and dihydrogen phosphate ions. The pH level of blood drops below 7.4 when the `H^(+)` in the blood increase. Hydrogen phosphate ions accept all additional `H^(+)` ions to re-establish the equilibrium between the hydroxide and hydrogen ions in the blood.
