1. Human lysosomes contain hydrolytic enzymes that are activated at a pH of 4.5-5.0. Which of the following factors could alter the structure integrity of a hydrolytic enyzme causing a loss of function? (MULITPLE ANSWERS – select all that apply) a. temperature below body temperature b. pH above 5.0 c. pH below 4.5 d. temerature above body temperature e. genetic mutation in hydrolytic enzyme gene

Which of the following is NOT true about lysosomes? Hydrolytic enzymes found in lysosomes are active in environments with low [H+]. Lysosomes are the main site for intracellular digestion. All of the above are true. The low pH of lysosomes is maintained by active transport of H+ from the cytosol.

Each day, the pancreas produces up to 1.5 L of pancreatic juices that enter the duodenum via the pancreatic duct. The pancreatic juices consist of water, salts, bicarbonate ions, and digestive enzymes. Bicarbonate ion raises the pH of the acidic chyme from the stomach, stopping the active ity of pepsin and allowing the pancreatic and intestinal enzymes to function. The various pancre. atic enzymes and their substrates are listed in Table 10.2. Table 10.2 Various enzymes produced by the pancreas...
