Question

Quizplus · Accepted Answer

The small intestine is responsible for completing protein digestion with the help of digestive enzymes secreted by the pancreas and intestinal cells.

Answer: B
 While the stomach also plays a role in protein digestion, it is not where it is completed. The stomach secretes acid and enzymes to begin breaking down proteins, but the majority of protein digestion occurs in the small intestine.
