- The order of successive steps in digestion is: a. absorption follows enzymatic hydrolysis. b. secretion of enzymes follows absorption of digestive material. c. mechanical processing follows enzyme secretion. d. mechanical processing follows enzymatic hydrolysis. e. enzymatic hydrolysis precedes secretion of digestive aids.The pH of human stomach acid ranges from 1.0 to 3.0, whereas a healthy esophagus has a pH of approximately 7.0. In gastroesophageal reflux disease (GERD), often called acid reflux, stomach acid flows backward from the stomach into the esophagus. Repeated episodes in which esophageal pH goes below 4.0, considered clinical acid reflux, can result in bleeding ulcers and damage to the esophageal lining. The data in the Figure, from a patient with GERD, show esophageal pH during a sleeping reflux event. How many minutes does it take to go from the peak of the reflux event (when pH is most acidic) to when the reflux event is over? Source: Based on T. Demeester et al. 1976. Patterns of gastroesophageal reflux in health and disease. Annals of Surgery 184:459469.Different regions of the digestive system specialize in ________ and _________ food and in __________ unabsorbed food residues.
- Pepsin is enzyme that found in the stomach. What do you think is the ideal temperature and pH for pepsin . Why?True or false Chemical digestion of protein occurs in the mouth. Saliva secretion increases when you think of appealing food.Pepsin is resistant to the denaturing effect of the low pH environment of the stomach. Thinking about the different digestive processes that occur in the small intestine, describe an adaptation shared by the digestive enzymes in that compartment.
- You eat a cheeseburger. Describe the process by which the proteins are broken down. Include the locations of each step. Explain how the final products of digestion are absorbed. Include where this happens, and where they go after. Explain what ingredients in the cheeseburger provide each type of nutrientYou just had a hamburger with sunny side egg on top . Describe the “journey” of fat through your digestive system beginning in the mouth to the rectum. Be sure to discuss how the fats are broken down from the fat globules to chylomicrons in the small intestine. Be sure to name them at every step.Which of the following words is missing in the following sentence: If you suck on a piece of bread, it will start to taste sweet after a while. This is because saliva contains the degrading enzyme ____________ which breaks down starch into ___________________. a) amylase; glucose b) amylase; maltos c) pepsin; maltos d) maltas; glucose
- Which association is incorrect?a. protein—trypsin d. starch—amylaseb. fat—lipase e. protein—pepsinc. maltose—pepsinChemical digestion of proteins is primarily done in the mouth. True FalseWhich of these substrate/enzyme pairs is correct? a. Lactose/cellulase b. Lipids/lipase c. Proteins/lactase d. Cellulose/pepsin
