H⁺ generated from CO₂ at the tissue level is buffered in transit between the tissues and the lungs primarily by which of the following? A)haemoglobin B)phosphate buffer system C) H₂CO₃:HCO₃^- buffer system D) plasma proteins

Question

Quizplus · Accepted Answer

Hemoglobin acts as a buffer and binds with hydrogen ions (H+) to form deoxyhemoglobin, which helps in buffering the acid produced during metabolism. As H⁺ is acidic in nature, hemoglobin present in red blood cells helps to buffer the acid during transit from tissues to lungs.
