Quizplus · Accepted Answer

Nitrogen is the correct answer because, under normal physiological conditions, it is not transported by hemoglobin. Hemoglobin primarily transports oxygen, carbon dioxide, and can also bind to carbon monoxide and nitric oxide, but it does not carry nitrogen in a significant amount. Nitrogen is mostly dissolved in the plasma and is not actively transported by hemoglobin.
