different enzymes on food during digestion of food

. The digested products are then absorbed back into the cell. In higher invertebrates and vertebrates, the digestion takes place in a specialised separate canal called the alimentary canal. There are different openings for ingestion and egestion. Each portion of the ca..

. They can directly enter the cell. The digestion may take place outside cells ( extracellular ) or within the cells ( intracellular ). In unicellular organisms the digestion is intracellular with the enzymes being present in vesicles. In more advanced multicellular fo..

Digestion starts in the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by the salivary carbohydrases which partially digests the food. The food is then swallowed with the help of lubrication provided by the sali..

Once the food is ingested into the mouth the action of the upper and the lower jaw crushes and grinds the food. This process is called mastification. This also stimulates the production of saliva. Saliva is thoroughly mixed with the food with the action of the jaws, te..

Food Webs - In nature, the food and feeding relationships of plants and animals are rarely as simple as the examples of food chains described above, because many animals eat more than one kind of food. On this account, different kinds of food..

Classification of food - On the basis of nutrients food can be classified into seven different groups: Carbohydrates Proteins Fats Vitamins Minerals Roughage Water Table 3. Composition of some common foods Food Carbohydrate Fat Protein Bread (Chapat..

Food Web - In nature, food chain relationships are not isolated. They are very complex, as one organism may form the food source of many organisms. Thus, instead of a simple linear food chain, there is a web like structure formed by these interlinked foo..

Salivary glands - They are glands found associated with the mouth and their secretion is called saliva. Saliva is a slightly alkaline secretion which contains 99% water. It consists of proteins like mucin which serves to lubricate the food and also helps in its passage along the alimentar..

Digestion in amoeba is intracellular taking place within the cell. The food taken in remains in a food vacuole or gastric vacuole formed by the cell membrane and small part of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic movements. ..
