Which of the following are the large molecules that are broken down into smaller molecules during digestion?

Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.
