Question

Quizplus · Accepted Answer

Urea is the major waste product of nitrogen metabolism. It is produced in the liver from ammonia, a by-product of protein metabolism, and is excreted by the kidneys in urine. Plasma proteins, glucose, and amino acids are not waste products of nitrogen metabolism. "PO₄" is not a valid answer choice.
