If the liver's urea cycle malfunctions due to genetic enzyme deficiency, which consequence follows for the patient?

💡 Explanation

Ammonia detoxification normally occurs via the urea cycle in the liver. When this cycle malfunctions, ammonia accumulates in the bloodstream because the liver can no longer effectively convert it to urea; therefore, ammonia toxicity rises, rather than bile production or glycogen changes.
