Critical Thinking Assignment 12: Digestion and Energy Balance The following questions concern the scientific basis behind claims made about the "raw food diet". The following is an excerpt from iVillage.co.UK. Why go raw? Proponents of the raw diet believe that enzymes are the life force of a food and that every food contains its own perfect mix. These enzymes help us digest foods completely, without relying on our body to produce its own cocktail of digestive enzymes It is also thought that the cooking process destroys vitamins and minerals and that cooked foods not only take longer to digest, but they also allow partially digested fats, proteins and carbohydrates to clog up our gut and arteries An article in the August 2005 issue of Oxygen magazine stated that plants and animals contain enzymes that are used in DNA repair and metabolism, and that these can be used by our cells if we consume foods raw, so that the enzymes do not become denatured. small 1. In what form and by what mechanism are carbohydrates absorbed through your intestine? (2 pts) 2. Enzymes of course are proteins. What effect do pepsin and a very low pH in our stomach have on proteins? G2 pts) a. What is the effect of intestinal and pancreatic peptidases and proteases on proteins and peptides? (2 pts) b. In what form and by what mechanism are proteins absorbed in adults? (See Sillvethom Figure 21-17) (2 pts) c. d. What is the likelihood of an adult absorbing a whole enzyme through their small intestine? (1 pt) e. How do you think your immune system would react to a whole foreign protein irn your blood?

Explanation / Answer

Ans1

Carbohydrate is complex component of food, during digestion process of carbohydrate through out of the alimentary tract it finally converted into simple food like glucose,fructose,galactose (monosaccaride) so in this form it absorbed.

Small intestine is the major site of absorption in alimentary tract, most of digestive food not absorbed by the simple diffusion but by active process it require energy for absorption. Monosaccharide absorb in bloodstream by simple or facilitated diffusion process. In facilitated diffusion carrier protein involve in transportation.
