What is the primary product of chemical digestion?

The primary product of chemical digestion is monomers. During the process of digestion, complex macromolecules such as proteins, carbohydrates, and fats are broken down into their simplest forms, which are the monomers. For proteins, this means they are broken down into amino acids; for carbohydrates, into simple sugars like glucose; and for fats, into fatty acids and glycerol.

Monomers serve as the building blocks for physical structures and functions within the body. They can be absorbed into the bloodstream and transported to cells where they are utilized for energy, growth, and repair. In essence, the digestion process transforms larger, complex molecules (polymers) into these smaller units (monomers), which the body can readily use.

In this context, while amino acids, carbohydrates, and other specific molecules may also be products of digestion, the overarching correct answer regarding what digestion ultimately produces is monomers since they encompass all types of basic units derived from food.
