The breakdown of large molecules into smaller ones that can be absorbed by cells is called hydrolysis.

Here's why:

* Hydro means "water"

* Lysis means "breaking down"

Hydrolysis involves the addition of a water molecule to break the bonds between monomers (the building blocks of large molecules). This process is essential for digestion and the absorption of nutrients.

For example:

* Carbohydrates are broken down into simple sugars like glucose.

* Proteins are broken down into amino acids.

* Lipids (fats) are broken down into fatty acids and glycerol.
