Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
Since there is no machinery in the body, it is a chemical breakdown.
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
Chemical
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.
The antonym for mechanical weathering is chemical weathering. Chemical weathering is the breakdown of rocks and minerals through chemical reactions, while mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.
The three factors that affect weathering are mechanical weathering (physical breakdown of rocks), chemical weathering (chemical changes in rocks), and biological weathering (weathering caused by living organisms).
Mechanical digesting is this that involve physical breakdown or movement of food not chemical. Actions like chewing and swallowing would be mechanical.
it do because it decrease the time the chemical breakdown takes place. if the food wasn't mechanically brokendown the chemicalbreakdown would have bigger pieces to breakdown causing the process to slow down
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.
