important buffer in the maintenance of the acid-base balance of the blood is:
A)fatty acids.
B)lactic acid.
C)protein.
D)carbohydrate.

Question

Quizplus · Accepted Answer

Protein is the most important buffer in maintaining the acid-base balance of the blood, as it can act as both an acid and a base, depending on the pH of its surroundings. This ability helps to prevent sudden changes in pH that could be harmful to the body. Protein is an important buffer in the maintenance of the acid-base balance of the blood. This is because proteins contain ionizable amino acids that can act as either a hydrogen ion acceptor or hydrogen ion donor, depending on the pH of the solution. This enables proteins to help regulate the pH of the blood by either releasing or accepting hydrogen ions as needed. Fatty acids and carbohydrates do not have this buffering capacity, and while lactic acid can act as a buffer, it is not as significant as protein in maintaining the acid-base balance of the blood.
