Best Answer: Probably the same as any other major... probably even shorter than some (such as pre-med), so 4 years. For my school, you need Intro, Research Methods ...
Digestion of foods in the small intestine. The small intestine continues the process of digestion and various enzymes are present there to break starches down further. These enzymes are called disaccharidases. The best known is lactase, which is the enzyme necessary to digest milk sugar. This enzyme is normally present in all young mammals who need this to digest mother's breast milk. With age and as breast feeding finishes, production of this enzyme ceases for life.
Chymosin and pepsin are the only two enzymes produced in the stomach. Chymosin is produced (in its active form) immediately after the birth in the stomachs of young mammals. In human babies, rennin is primarily associated with the coagulation of milk.This property assists in the digestion of milk in infants.urther, it inhibits the precipitation of the other three molecules. Rennin, which is an active enzyme in rennet (a complex of enzymes present in any mammalian stomach), masks kappa-casein so that the other three molecules get precipitated. Importance of Rennin in the Human Body.
