Detailed explanation-1: -Complete answer: The process of conversion of ammonia into urea is known as the urea cycle which occurs in the liver and then urea is transferred to the kidney for excretion.

Detailed explanation-2: -The main purpose of the urea cycle is to eliminate toxic ammonia from the body. About 10 to 20 g of ammonia is removed from the body of a healthy adult every day. A dysfunctional urea cycle would mean excess amount of ammonia in the body, which can lead to hyperammonemia and related diseases.

Detailed explanation-3: -Final answer: Ammonia. is converted into urea in the Liver.

Detailed explanation-4: -Second, both intracellular and extracellular buffers are used to buffer endogenous and exogenous acid loads and must be replenished to maintain acid-base homoeostasis. The kidneys produce “new bicarbonate” to do so, and the primary mechanism of new bicarbonate generation involves renal ammonia metabolism.
