Which of the following organs is associated with deamination of proteins?

Explanation

This question is asking which organ in the body is responsible for the process of deamination of proteins. Deamination is the removal of an amine group from a molecule. Among the options given, the correct answer is the liver. The liver is the largest glandular organ in the body and is responsible for many important metabolic functions. One of these functions is the processing of proteins. The liver breaks down proteins into their component amino acids, and then removes the amine group from each amino acid in a process called deamination. The amine group is converted into ammonia, which is then converted into urea and excreted from the body through the kidneys in the form of urine. The other options listed, such as the lung, stomach, kidney, and heart, do not play a significant role in the deamination of proteins. The lung is involved in respiration, the stomach in digestion, the kidney in filtration and excretion of waste products, and the heart in circulation of blood. In summary, the liver is the organ associated with deamination of proteins in the body. It breaks down proteins into their component amino acids and removes the amine group through the process of deamination.
