With the entry of food into the alimentary canal, the salts and water are found absorbed in it. But other particles composing the food are so large that they cannot be absorbed directly. It is necessary to break down them to fine particles for diffusion. This process is called digestion and is brought about by […]
The difference between Extracellular and Intracellular Digestion is that in the former digestion occurs in the food vacuoles within cells whereas in the later digestion occurs outside of cells in the lumen of the alimentary canal.
The component of the normal diet includes carbohydrates, lipids, proteins, vitamins, minerals and water. Out of these constituents water, vitamins, minerals, free monosacharides and free amino acids can be absorbed interest of body absent such.
Complex food stuffs like carbohydrates, fat and protein need to be digested or hydrolysed before assimilation. The final product of carbohydrate digestion is monosacharides, that of fats are fatty acids and glycerol and of protein are amino acids.
Digestion is a hydrolytic process in which complex food materials are mechanically and enzymatically broken down into simpler soluble forms. Proteins are polymers of amino acid residues which are joined end to end by peptide bonds. Proteolytic enzymes break down the peptide bonds.
