Final answer:
Hydrolases are enzymes that break down large molecules into smaller subunits through the addition of water, aiding digestion and energy release.
Step-by-step explanation:
Hydrolases are enzymes that specific function is to catalyze the hydrolysis reactions, meaning they break down large molecules into smaller subunits through the addition of water. For instance, different hydrolases such as amylase and lipase are responsible for the breakdown of carbohydrates and lipids, respectively. During hydrolysis, a molecule of water is split into a hydrogen atom (H) and a hydroxyl group (OH), which are then added to the molecule being broken down. This process is essential for digestion in the human body as it allows for the absorption of nutrients in the intestine and the release of energy stored within molecules to be used by the cells.
