Which of the following statements about the transport of the absorbed products of fat digestion is true? a. Free fatty acids and monoglycerides are transported to the liver via the hepatic portal vein b. Products of fat digestion first go to the lymphatic system and then to the cardiovascular system c. Chylomicrons are transported to the liver via the hepatic portal vein to be processed d. Products of fat digestion are absorbed in the large intestine e. None of the choices are correct Which enzymes cleave peptides into amino acids that are readily absorbed into absorbed into intestinal epithelium? a. Pancreatic lipase b. Bile c. Pepsin d. Brush-border (along intestinal lumen) enzymes e. Salivary amylase Which of the following enzymes is most active at an acidic pH? a. Amylase b. Trypsin c. Lipase d. Pepsin In the digestion lab, a. Amylase worked well in HCl, because the tube that contained amylase and HCl changed iodine's color. b. Enzyme and bile salts were breaking down fats, because the tubes that contained enzyme and bile increased in pH the most. c.
