digestion
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
No, the pancreas is involved in chemical digestion, as it secretes enzymes which catalyze the breakdown of food molecules.
The answer is digestion. It's the process that breaks down food into small molecules so that they can be absorbed and moved into the blood. From the blood, food molecules are transported across the cell membrane to be used by the cell. Unused molecules pass out of your body as wastes. There's two types of digestions: Mechanical and Chemical. Mechanical digestion takes place when food is chewed, mixed, and churned. Chemical digestion occurs when chemical reactions occur that break down large molecules of food into smaller ones.
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.
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
Chemical
Oxidising - reducing reactions are important for the synthesis and breakdown of biological molecules?
Mechanical digesting is this that involve physical breakdown or movement of food not chemical. Actions like chewing and swallowing would be mechanical.
All of chemical reactions in cells breakdown molecules and make molecules.

This is a chemical change. Pepsin catalyzes the chemical breakdown of food.
