how does mechanical digestion enhance chemical digestion

Breaking down food into simpler forms is called digestion. Digestion is both mechanical and chemical . In mechanical digestion, food is physically broken down into smaller particles by processes such as chewing. Chemical ..

Digestion is defined as the process by which complex food molecules are broken down into simpler molecules, so that they can be absorbed by the body. Digestion is mechanical and chemical . In mechanical digestion, food is physically br..

Mechanism of Digestion - Once the food is ingested into the mouth the action of the upper and the lower jaw crushes and grinds the food. This also stimulates the production of saliva. Saliva is thoroughly mixed with the food with the action of the jaws, teeth, inner walls of che..

Digestion starts at the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by enzymes of salivary juice, the salivary carbohydrases which partially digest the food. The food is then swallowed with the help of lubrication provided by the salivary..

Renin is present only in young children. It digests the milk protein, casein. Casein is hydrolysed into paracasein which gets precipitated as insoluble calcium paracaseinate. This is called coagulation. Renin secreted by the gastric mucosa of the calf is extracted to make rennet tab..

Saliva is thoroughly mixed with the food with the action of the jaws, teeth, inner walls of cheeks and tongue. The food is formed into bolus..

A known mass (0.3 to 0.5 g) of the given organic compound is digested with concentrated H 2 SO 4 , in presence of a small quantity of potassium sulphate and copper sulphate in a Kjeldahl's flask. Potassium sulphate raises the boiling point of sulphuric acid and copper sulphate catalyzes ..

Rinse mouth 2 to 3 times to remove any food particles and collect saliva in three test-tubes labelled A, B and C. To B add half the quantity of 2% starch solution. To C add boiled saliva. Leave them for 5 minutes. At the end of five minutes, a) Addition of iodine to A gives no blue colour. Why? Th..

Digestion is actually carried out by enzymes but the secretion of these enzymes is controlled by the nervous system and endocrine syst..
