Question

Quizplus · Accepted Answer

Albumin is the main protein buffer in blood plasma, as it can bind both acidic and basic compounds and help to maintain a stable pH in the blood. Hemoglobin is primarily responsible for carrying oxygen in the blood, while complement is a group of proteins involved in the immune response. Fibrin is a protein involved in blood clotting, and calmodulin is a protein involved in calcium signaling. None of these proteins have a significant buffering capacity in the blood.
