Here's why:
* Enzymes are biological catalysts: They speed up chemical reactions without being consumed in the process.
* Specific to reactions: Each enzyme is designed to work on a specific type of molecule (like carbohydrates, proteins, or fats).
* Digestive enzymes: Our bodies produce a variety of enzymes specifically for breaking down food in the digestive system.
Examples of digestive enzymes:
* Amylase: Breaks down carbohydrates into sugars.
* Protease: Breaks down proteins into amino acids.
* Lipase: Breaks down fats into fatty acids and glycerol.
So, while many chemicals might be involved in digestion, the enzymes are the key players in speeding up the breakdown of food into usable nutrients.
