Choose the correct order of enzyme activities in protein digestion.

Question

Quizplus · Accepted Answer

The correct order of enzyme activities in protein digestion is pepsin (in the stomach), followed by trypsin and chymotrypsin (in the small intestine), and then carboxypeptidase (also in the small intestine). This breakdown produces dipeptides, which are then broken down by dipeptidases into free amino acids. Therefore, option A and B are incorrect, while option D is the partial correct order of the activation of trypsinogen, a precursor enzyme that is converted into trypsin by enteropeptidase. However, it does not include other enzymes involved in protein digestion.
