Which event occurs in the small intestine?

Question

Quizplus · Accepted Answer

The small intestine is primarily responsible for the continuation of protein digestion. While some carbohydrate and fat digestion occurs in the small intestine, the majority of carbohydrate digestion occurs in the mouth and small intestine, and the majority of fat digestion occurs in the stomach and small intestine. The small intestine is also the site of nutrient absorption, which occurs after digestion. Therefore, option E is incorrect. Option A is partially correct, as some carbohydrate digestion does occur in the small intestine, but it begins in the mouth with the action of amylase in saliva. Option C is also partially correct, as chemical digestion of all macronutrients (carbohydrates, fats, and proteins) occurs throughout the digestive system, starting with saliva in the mouth. However, the small intestine is not specifically known for the beginning of chemical digestion.
