What process do digestive enzymes use to break down food?

Digestive enzymes play a crucial role in the breakdown of food during digestion through a process known as hydrolysis. Hydrolysis involves the chemical addition of water to split larger molecules into smaller components. Specifically, enzymes catalyze the cleavage of chemical bonds in macromolecules such as carbohydrates, proteins, and fats, leading to the formation of simpler molecules like sugars, amino acids, and fatty acids.

This process is essential for nutrient absorption; it allows the body to convert complex food substances into their more absorbable forms. Hydrolysis occurs throughout the digestive system, beginning in the mouth with saliva and continuing in the stomach and small intestine, where various enzymes act on each type of macromolecule.

While fermentation, emulsification, and oxidation are related processes in digestion or metabolism, they do not directly describe the specific enzymatic breakdown of food. Fermentation, for example, is a metabolic process that converts sugars to acids, gases, or alcohol in the absence of oxygen, which is not how digestive enzymes operate. Emulsification refers to the breakdown of fat globules into smaller droplets, which aids digestion but does not involve enzymes breaking chemical bonds through water addition. Oxidation is a chemical reaction involving the loss of electrons, often related to energy production rather
