General Biology Prep for Drugs & Enzyme Inhibition Activity Your readings .Please review Concept 8.4 (paying particular attention to enzyme inhibitors) Read Concepts 41.1 and 41.2 Read "Bile production by the liver" on p. 903 .Review the fat digestion section of Figure 41.14 and . Read the "Regulation of Energy Storage" section of Concept 41.5 Read the website page: http://www.livestrong.com/article/222560-what-is-meaning-of-fat-soluble- vitamins/ The following questions will help guide your readings and ensure that you are prepared for the in-class activity 1. An inhibitor that resembles the substrate of an enzyme is likely to be a Cosspei_inhibitor and bind the enzyme at te achue ais lcsenc 2. What are the four classes of essential nutrients? 3. List one water-soluble and two fat-soluble vitamins. Provide an example of a food you should ingest to properly absorb a water soluble vitamin. Do the same for a fat soluble vitamin. 4. What are the four stages of food processing? 5. How does digestion occur: DEHYDRATION reactions or HYDROLYTIC reactions? 6. Why must digestion occur BEFORE absorption? 7. With respect to fat digestion a. What is needed to break up fat globules (and what is the source of this molecule?) b. What enzyme digests fats, and where is this enzyme made? c. What are the products of fat digestion? (and therefore what is actually absorbed after a high-fat meal?) 8. What are some health risks associated with being obese?Explanation / Answer
1. An inhibitor that resembles the substrate of an enzyme is likely to be a competitive inhibitor and bind the enzyme at its active site.
2. 4 classes of essential nutirents are: essential amino acids, essential fatty acids, vitamins and minerals.
3. water soluble vitamin: Vitamin B
Fat soluble vitamin: vitamin A, D, E
water should be taken to abosrb water soluble vitamins
Fatty foods such as olive oil, avacado, nuts, should be injested to absorb fat soluble vitamins
4. 4 stages of food peocessing are ingestion, digestion, absorption and elimination.
5. Digestion of food is an example of hydrolytic reactions.
