Exam II 1. Lipoprotein lipase: a. Is anchored on the cell membranes in blood vessels b. is secreted by the pancreas into the small intestine c. synthesizes lipoproteins from free fatty acids and glycerol d. releases glycerol and free fatty acids from chylomicrons and lipoproteins 2. compounds that are classified as lipids include: a. dipeptides b. amino acids c. diglycerides h. urea 3. essential fatty acids include: a. butyric acid b. oleic acid c. stearic acid d. lactic acid 4. adipocytes a. have a lower water content than muscle cells b. are the primary site for triglyceride synthesis and storage c. contain up to 85% lipid d. release large amounts of fatty acids into the blood after meals in monogastric animals 5. essential amino acids include: a. tryptophan b. linoleic acid c. methionine d. acetate 6. enzymes used to digest proteins include: a. dipeptidases b. lipases c. salivary amylase d. chymotrypsin 7. in the small intestine, proteins are broken down to: a. diglycerides b. micelles c. free amino acids d. disaccharides 8. transamination reactions: a. transfer an amino group from an maino acid to an alpha-keto acid b. are used to synthesize amino acids as needed c. are used to synthesize essential fatty acids d. convert ammonia to urea 9. Triglycerides: a. are comprised of three amino acids linked by peptide bonds b. are comprised of a molecule of glycerol and three fatty acids c. are monogastric carnivores d. cannot provide energy to ruminant animals 10. Potential functions for vitamins include: a. co-factors for enzymes b. hormone like-activity c. provide energy as they are oxidized d. combine together in chains as storage form for energy

True/Flase 14. ketones are partially oxidized proteins T F 15. Bile salts produce smaller lipid spheres with a greater surface area for digestion T F 16. During beta-oxidation of fatty acids, no energy is derived T F 17. The two carbon units generated during beta-oxication of fatty acids enter glycolysis as acetyl-CoA T F 18. During fatty acid biosynthesis, two carbon units are repeatedly added from the methyl end T F 19. Ruminants are unable to synthesize fatty acids from glucose T F 20. Ruminants can tolerate up to 20% fat because they do not have a gall bladder T F 21. Small intestinal cells (enterocytes) utilize less than 1% of absorbed amino acids
