Since there is no machinery in the body, it is a chemical breakdown.
Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.
This is a chemical change. Pepsin catalyzes the chemical breakdown of food.
digestion
The large intestine does not perform any digestion whatsoever. It is part of the gastrointestinal tract, but it only performs mainly absorption, as in water, some minerals, and some vitamins.
mechanical weathering and chemical weathering are related because their both are types of weathering
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
Chemical
Mechanical digesting is this that involve physical breakdown or movement of food not chemical. Actions like chewing and swallowing would be mechanical.
chemical and mechanical
This is a chemical change. Pepsin catalyzes the chemical breakdown of food.
The small intestine completes the process of chemical digestion.
Mastication, commonly known as chewing, is the term for the mechanical breakdown of food in the mouth.
digestion
Peristalsis. The movement of muscles bringing the food to the stomach.
No, the pancreas is involved in chemical digestion, as it secretes enzymes which catalyze the breakdown of food molecules.
