Hello, Please answer the following attached Biology question correctly and fully. Thanks! **Question:**What is the pH inside your stomach? Do you think proteins are completely broken down in your stomach? Why or why not?---**Response Section:**[This section is where students would be expected to write their answers. The purpose of this exercise is to encourage understanding of stomach pH levels and the process of protein digestion in the human body.]

The pH of a digestive organ is based on the substances that are secreted in it. The pH of the gastric fluid contributes to the activation of the proteolytic enzymes in it. The stomach has the lowest pH than other organs of the digestive system. Mechanical digestion of the protein in the food starts in the mouth while the chemical digestion of protein begins in the stomach. The peptide bonds that connect the amino acids in the protein are broken down by the proteolytic enzymes in the stomach and small intestine digestive fluids. The mucosa of the stomach secretes gastric juice that contains water, hydrochloric acid, organic substances such as pepsin and mucus as well as electrolytes. The presence of hydrochloric acid in the gastric juice contributes to the low pH of about 1 to 3 in the stomach. The presence of pepsin in the gastric juice allows the gastric juice to break down proteins into smaller peptides and amino acids. These peptides are then digested in the small intestine by the enzymes such as trypsin in the pancreatic juice. Hence, proteins are not fully digested into amino acids in the stomach. It is the small intestine where the protein digestion gets completed.
