Mechanical digestion is the physical mashing and pulling apart of food like chewing your food. Chemical digestion uses acids and enzymes to chemically break down the food until it is small enough to be absorbed through the wall of the small intestine.

The two kinds of digestion in the digestive system are mechanical digestion, which involves physically breaking down food into smaller pieces through chewing and grinding, and chemical digestion, which involves the breakdown of food molecules into nutrients by enzymes and acid in the digestive tract.
Degradation and some oxidation to smaller molecules
The process of breaking down complex molecules into simpler ones, such as digestion of food in the stomach, requires hydrolytic enzymes. These enzymes catalyze the breaking of chemical bonds by adding water molecules, helping to convert large molecules into smaller, digestible ones for absorption by the body.
We call the chemical that breaks down large molecules of food into smaller molecules "enzymes." Enzymes play a crucial role in the digestion process by catalyzing the breakdown of macromolecules like proteins, carbohydrates, and fats into smaller units that can be absorbed by the body for energy and nutrients.
Digestion is a chemical process that breaks down food particles into smaller molecules through the action of enzymes. It involves the breakdown of complex molecules into simpler ones through chemical reactions.
The type of digestion where food is digested is called mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food into smaller pieces, while chemical digestion involves the breakdown of large molecules into simpler substances with the help of enzymes.
Digestive juices and enzymes break down the complex food materials into simpler compounds and that is how they facilitate in digestion.
Digestive enzymes actually help speed up the digestion process by breaking down proteins, carbohydrates, and fats into smaller molecules that can be absorbed by the body more easily. They work in coordination with the body's natural digestive processes to enhance overall digestion and absorption of nutrients.
Mechanical digestion is not considered a chemical change. Mechanical digestion involves physically breaking down food into smaller pieces through chewing and mixing with digestive juices, whereas chemical digestion involves enzymes breaking down macromolecules into smaller molecules.
