Q1. Choose two products from your daily diet as in butter or salad dressing and find similar products that use fat substitutes. Make a list of all the fat substitutes that you find listed on the ingredient labels of the products. Indicate what type of fat substitute you found such as the synthetic fat Olestra. Find out how many calories you will have saved by eating this reduced-fat product instead of the high-fat one. Compose an argument discussing why you would or would not select the reduced-fat product as part of a healthy diet. Include in your discussion the RDA guidelines recommending less than 30 percent of total calories come from fat.
Q2. Cells of the pancreas will incorporate radioactively labelled amino acids into proteins. This "tagging" of newly synthesized proteins enables a researcher to track their location by detecting where the radioactivity is. In this case, we are tracking an enzyme secreted by pancreatic cells. What is its most possible pathway?
