Question

Quizplus · Accepted Answer

Ammonia is a highly toxic by-product of metabolism that can disrupt normal cellular function and cause liver and brain damage if not removed from the body efficiently. Urea, lactic acid, and carbon monoxide are also by-products of metabolism, but they are less toxic than ammonia. Urea is a relatively harmless nitrogen-containing compound that is formed in the liver and excreted by the kidneys. Lactic acid is produced during anaerobic metabolism in muscle cells and can cause muscle fatigue and soreness, but is not considered particularly toxic. Carbon monoxide is a poisonous gas that can interfere with cellular respiration and cause headaches, dizziness, and even death, but it is not a by-product of normal metabolism.
