different enzymes that act 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 b..

. The bolus thus partially digested is now called the chyme. Chyme is then passed into the small intestine, the opening of which is guarded by the pyloric sphincter. The first portion of the small intestine, the duodenum gets the pancreatic and the bile juice. The intestinal lumen has an ..

. The food then moves into the stomach. The opening is controlled by the cardiac sphincter which is a muscular ring. The stomach opens only in response to swallowing. Here the proteins are broken down into proteoses and peptones by the action of pepsin and the soluble milk protein caesino..

Digestion in Amoeba - 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 c..

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. ..

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..
