Question

Quizplus · Accepted Answer

The end products of protein metabolism, such as urea and creatinine, are excreted by the kidneys through urine. The stomach and gallbladder are not involved in excreting protein metabolites, and although the liver does metabolize proteins, it does not excrete the end products. The end products of protein metabolism, such as urea, creatinine, and uric acid, are excreted by the kidneys in the form of urine. The stomach is involved in protein digestion, but does not excrete protein waste products. The liver is involved in the breakdown and synthesis of proteins, but does not directly excrete protein waste products. The gallbladder stores and releases bile, which aids in fat digestion, but does not have a role in protein metabolism or excretion.
