Which of the Following is a Nitrogenous Waste

Question

Which of the following is a nitrogenous waste?
A)Ammonia
B)Urea
C)Creatinine
D)All apply.

Accepted Answer

All three options (ammonia, urea, and creatinine) are nitrogenous wastes produced by the breakdown of proteins in the body. Ammonia is the most toxic of the three and is converted to urea by the liver before being excreted in urine. Creatinine is a waste product generated by the breakdown of creatine phosphate, which is found in muscle tissue.
