HESI Biology - Why Exam Edge Sample Questions

 All of the following happen in the small intestines EXCEPT:

Correct Answer:
 pepsin breaks down proteins


the small intestines are a critical site for the digestion and absorption of nutrients. this lengthy portion of the gastrointestinal tract is primarily responsible for breaking down food into its molecular components, which can then be absorbed into the bloodstream. various enzymes and secretions facilitate this complex process. for instance, bile, produced by the liver and stored in the gallbladder, is released into the small intestines where it emulsifies fats. this action breaks down large fat globules into smaller droplets, which increases the surface area for enzymes to act upon, enhancing fat digestion.

however, not all digestion-related processes occur in the small intestines. the statement that "pepsin breaks down proteins" in the small intestines is incorrect. pepsin is an enzyme that is specifically secreted by the stomach. it plays a crucial role in the initial stages of protein digestion by breaking down the protein structures into smaller peptides. this action occurs in the acidic environment of the stomach, which is uniquely suited to pepsin’s function. once the partially digested food mixture (chyme) leaves the stomach and enters the small intestine, the ph changes, rendering pepsin inactive. thus, protein digestion by pepsin is exclusive to the stomach and does not continue in the small intestines.

in the small intestines, other enzymes take over the protein digestion process. these enzymes, such as trypsin and chymotrypsin, are secreted by the pancreas and activated in the small intestine to further break down peptides into amino acids. this highlights the collaborative nature of the digestive system, where different organs contribute specific functions at various stages.

therefore, while it is true that most digestion and all nutrient absorption is completed in the small intestines, the statement that pepsin breaks down proteins in this part of the digestive tract is incorrect. pepsin's activity is confined to the stomach, making it an exception in the context of protein digestion in the small intestines. this distinction is essential for understanding the specialized functions of different parts of the digestive system.
