Detailed explanation-1: -Amino acids are the monomers that make up proteins. Specifically, a protein is made up of one or more linear chains of amino acids, each of which is called a polypeptide.

Detailed explanation-2: -The monomers of proteins are amino acids.

Detailed explanation-3: -Pepsin is secreted by peptic or chief cells as proenzyme pepsinogen then in the duodenum by trypsin, chymotrypsin, dipeptidase, exopeptidase, etc. So, the chemical digestion of protein starts in the stomach and ends in the small intestine. Hence, the end product of protein digestion is amino acids.

Detailed explanation-4: -When you eat food the body’s digestive system breaks down the protein into the individual amino acids, which are absorbed and used by cells to build other proteins and a few other macromolecules, such as DNA.

Detailed explanation-5: -When you eat food, the body’s digestive system breaks down dietary protein into individual amino acids, which are absorbed and used by cells to build other proteins and a few other macromolecules, such as DNA.
