The form of hemoglobin with iron in a reduced state and bonded to carbon monoxide is
A)oxyhemoglobin.

Question

Quizplus · Accepted Answer

The form of hemoglobin with iron in a reduced state and bonded to carbon monoxide is known as carboxyhemoglobin. The carbon monoxide binds to the reduced iron in the heme group of hemoglobin, preventing oxygen from binding to it and reducing the oxygen-carrying capacity of the blood. This is a dangerous condition as it can cause hypoxia or oxygen starvation in the body.
