What is the role of carbaminohemoglobin in carbon dioxide transport?

A It helps to regulate oxygen binding to hemoglobin
B It is the primary mechanism for transporting carbon dioxide in the blood
C It helps to buffer excess hydrogen ions in the blood
D It plays a minor role in carbon dioxide transport, accounting for about 5-10% of transported CO2 ✓

Explanation

Carbaminohemoglobin plays a minor role in carbon dioxide transport, accounting for about 5-10% of transported CO2, with the majority being transported as bicarbonate ions.
