Which of these statements does NOT describe 2,3-bisphosphoglycerate

D)It affects the degree of binding of oxygen to haemoglobin.

Question

Quizplus · Accepted Answer

2,3-bisphosphoglycerate (2,3-BPG) is produced within red blood cells (A), its production is inhibited by HbO₂ (B), and it affects the degree of binding of oxygen to hemoglobin (D). However, its concentration increases whenever Hb in the arterial blood is chronically undersaturated, as it helps to facilitate the release of oxygen from hemoglobin (reverse of statement C).
