Question

multiple choice question
chemical digestion of ______ begins in the stomach.
o protein and fat
o sugar and vitamins
o nucleic acids and proteins

Explanation:

In the stomach, pepsin (an enzyme) starts the chemical digestion of proteins. Nucleic acid digestion also begins in the stomach to some extent. Fat digestion mainly starts in the small intestine. Sugar (carbohydrate) digestion begins in the mouth (salivary amylase). Vitamins are absorbed rather than digested chemically in a traditional sense like macromolecules.

Answer:

nucleic acids and proteins
