chemical digestion
Nutrients are substances that are absorbed by the body through the process of digestion.
The process by which food is broken down into simpler substances is called digestion. This involves the mechanical and chemical breakdown of food in the digestive system, leading to the absorption of nutrients by the body.
There are many. Digestion is a twofold process; physical digestion and enzymatic digestion. Physical digestion is the act of eating food to break it into smaller parts. Enzymatic digestion is where enzymes (chemical compounds produced by the body) break the food down at a molecular level. Enzymes include salivary amylase, pepsin, lipase, trypsin and many, many more.
Mechanical digestion. The actual grinding and physical breaking down of food. Chemical digestion breaks down food using chemicals/enyzyms and chemical reactions.
These substances are called nutrients.
chemical changes
The processes are called chemical reactions.
