The following three questions refer to material you were to read in preparation for class. These questions require you to write a three or four sentence response. It is OK to answer 'I don't know' - but STATE WHY you are confused! (Don't just say 'I don't know' - you probably DO!) Each WarmUp worth 3 points if answered on time and must be submitted via the web. See notes page for prior Warm Ups and student responses.

Please enter a nickname (in case your answer is used in class!)

QUESTION 1: In your own words, what are prions, and how do they cause fatal brain diseases?

QUESTION 2: Starch (like bread, pasta) is a glucose polymer that gives us energy, but cellulose, an almost identical glucose polymer, is indigestible. Why do you think that ONE of these almost identical molecules can be digested, while the other can't? Why is cellulose (non-nutritive and indigestible) a very necessary part of our diet?

QUESTION 3: Trans fats have been in the news a lot lately, and have been increasingly implicated in development of heart disease. Why do large food manufacturers like Kraft prefer to use partially hydrogenated oil when baking cookies, cakes, and crackers?

QUESTION 4 (optional): What do you think of the recent lawsuits about the dangers of trans fats in snack foods? (See "Lawyer Sues Kraft for selling Oreos to Kids"). Comment from any perspective you choose...Kraft, a parent, a child, an oreo-lover, a lawyer!
