3 Nitrites effectively induce methaemoglobinaemia and the resultant ferricheme has a greater affinity for H2S than cytochrome-coxidase, thereby freeing cytochrome-c oxidase and allowing aerobic metabolism to resume.
Furthermore, CO also binds to the proteins myoglobin and cytochrome-c oxidase, which are found in the cardiac and skeletal muscles.
