ANATOMY

Detailed explanation-1: -The urea cycle is a process in which waste (ammonia) is removed from the body. When you eat proteins, the body breaks them down into amino acids. Ammonia is produced from leftover amino acids, and it must be removed from the body.

Detailed explanation-2: -The role of enzymes Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.

Detailed explanation-3: -The urea cycle is the primary metabolic pathway involved in the removal of nitrogenous waste produced from breakdown of protein and other nitrogen containing compounds.

Detailed explanation-4: -Molten urea decomposes into ammonia gas and isocyanic acid: CO(NH 2) 2 → NH 3 + HNCO.

Detailed explanation-5: -Ammonia and carbon dioxide (CO2) react exothermically to produce the carbamate salt, which is then heated to form urea. The heat produced in the first reaction drives the second.
