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.
Rennin enzymes are produced by the stomach cells of young mammals. Rennin is secreted in large amounts right after the birth and then its production gradually drops off. It is then eclipsed in importance by the Pepsin enzyme.epsin and rennin are the only two enzymes produced in the stomach. Rennin is produced as the inactive prorennin. When milk enters the stomach, prorennin is activated by the hydrochloric acid in the gastric juice and converted into the active rennin enzyme. slide 2 of 4.
