What is the process of changing food into simpler substance with the help of enzymes?

The process of changing food into simpler substances with the help of enzymes is called digestion. Enzymes, which are biological catalysts, break down complex molecules in food into smaller, absorbable units. For example, amylase breaks down starch into sugars, while proteases break down proteins into amino acids. This enzymatic action occurs primarily in the digestive system, allowing nutrients to be efficiently absorbed into the bloodstream for use by the body.
