Here's how it works:
* Enzymes are the key players in digestion. These are biological catalysts that speed up chemical reactions. Different enzymes are specialized to break down different types of food molecules, like carbohydrates, proteins, and fats.
* The digestive system provides the environment for these reactions to occur. This includes:
* The mouth, where mechanical breakdown (chewing) and the enzyme amylase begin the process of breaking down carbohydrates.
* The stomach, where strong acids and pepsin break down proteins.
* The small intestine, where most of the chemical digestion takes place with the help of enzymes from the pancreas and bile from the liver.
* The large intestine, where water is absorbed and waste is formed.
In summary, digestion is a series of chemical reactions that break down food into smaller molecules that the body can absorb and use for energy, growth, and repair.
