DIGESTIVE SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When large proteins are chemically digested, they are broken up into many smaller
A
amino acids
B
enzymes
C
simple sugars
D
None of the above
Explanation: 

Detailed explanation-1: -Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.

Detailed explanation-2: -During digestion, proteins are broken down into amino acids through hydrolysis. The amino acids dissolve in our blood and are carried to tissues and organs. There, the amino acids are either used as a source of energy or are assembled into proteins through condensation polymerization.

Detailed explanation-3: -Trypsin and chymotrypsin break down large proteins into smaller peptides, a process called proteolysis. These smaller peptides are catabolized into their constituent amino acids, which are transported across the apical surface of the intestinal mucosa in a process that is mediated by sodium-amino acid transporters.

Detailed explanation-4: -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.
