What do enzymes break down into simple sugars in the body?

Enzymes are biological catalysts that facilitate biochemical reactions in the body, including the breakdown of macromolecules. In the case of carbohydrates, specific enzymes, known as carbohydrases or amylases, act on complex carbohydrates such as starch and glycogen, breaking them down into simpler sugars like glucose and maltose. This process is crucial for digestion, as it allows the body to convert carbohydrates consumed in food into glucose, which serves as an important energy source for cells.

By efficiently breaking down carbohydrates into simple sugars, enzymes play a vital role in metabolic processes, enabling the absorption of these sugars into the bloodstream for use as energy. This is a key aspect of nutrition and energy production within the body.

The other options—fat, protein, and water—are not primarily broken down into simple sugars by enzymes. Fat is metabolized into fatty acids and glycerol, protein is broken down into amino acids, and water does not undergo a breakdown process in the same context as macromolecules. Thus, the correct understanding of enzyme function in relation to carbohydrates underlines why the correct answer is the breakdown of this macromolecule into simple sugars.
