Carbohydrate Assignment (65 Points) Due 2/14/21 by 11:59pm 1. What are the two main classes of carbohydrates? (2) - Simple and Complex 2. Classify the following as either complex or simple (5) Name Complex or Simple polysaccharides Complex Glucose Simple Disaccharide Simple Starch Complex Galactose Simple 3. What is the differences between dietary and functional fiber? (2) - Dietary fiber is naturally found in foods, Functional Fiber is added to food for beneficial effect 4. True or False: Examples of insoluble fiber are pectin in fruits and psyllium. (2) - False 5. Name 2 places that glycogen is stored? (2 responses) (2) - Liver and Muscle cells 6. Order the steps of carbohydrate digestion: (5) a. Fiber continues to the large intestine, where some is metabolized by bacteria in the colon and the majority eliminated in your stool b. Saliva contains amylase enzyme, which starts breaking down amylose and amylopectin into smaller starch units and maltose c. Maltose and other disaccharides are broken down to monosaccharides and absorbed into blood d. In small intestine, pancreatic amylase breaks down remaining starch into maltose - B, D, C, A 7. Name three signs of lactose intolerance: (4) - Nausea, cramps, bloating 8. Your friend just found out that he is lactose intolerant. What advice or recommendations would you give him to still enjoy products with lactose? Include at least 3 suggestions. (5) - Gradually add dairy products to your diet, try reduced-lactose milk and dairy products, and eat smaller amounts throughout day rather than large amount at one time. 9. Which organ releases insulin? (2) - Pancreas

10. What regulates glucose in the blood? (2) A. Insulin B. Hormones C. Glucagon D. None of the above E. All of the above 11. Briefly describe glycogenesis and the stages. (5) - Glycogenesis is the biological process of forming glycogen from glucose , the simplest cellular sugar. The body creates glycogen through the process of glycogenesis to store these molecules for use later, when the body does not have readily available glucose. When glucose enters the glycogenesis process, it must be acted on by a number of enzymes. the glucose molecule interacts with the enzyme glucokinase, which adds a phosphate group to the glucose. In the next step of glycogenesis, the phosphate group is transferred to the other side of the molecule, using the enzyme phosphoglucomutase. A third enzyme, UDP-glucose pyrophosphorylase, takes this molecule and creates uracil- diphosphate glucose. This form of glucose has two phosphate groups, as well as the nucleic acid uracil. These additions aid in the next step, creating a chain of molecules. 12. Correctly identify Glycogenolysis and gluconeogenesis (4) Definition Name Directs release of glucose from stored glycogen in liver Glycogenolysis making glucose from noncarbohydrate sources, mostly protein Gluconeogenesis 13. How does glucose effect the breakdown of fat when fasting? (4) - Without glucose, fat can't be broken down completely and acidic ketone bodies are produced. 14. When in starvation, what order will the body use the macronutrients for energy? (2) A. carbs, protein, fat B. Protein, fat, carbs, C. carbs, fat, protein 15. What is the minimum amount of carbohydrates in grams needed per day for brain function? (2) - 130 g 16. Identify and explain the benefits of 4 of the best carbohydrate food sources. (5)
