Directiоns: Chооse three (3) of the following four (4) questions to аnswer in its entirety. Eаch question is worth 10 pts. Be specific аs to which three questions you want graded! Question 1 As a food scientist, you have been asked to develop a prebiotic milkshake, specifically to include fibers that are metabolized by colonic bacteria. a. Will you use cellulose? Why or why not? (2 pts) b. Will you add fructans? Why or why not? (2 pts.) c. Name 3 byproducts produced when colonic bacteria breakdown fibers. (3 pts) d. Consistent evidence shows that soluble fibers can lower the levels of cholesterol in many people with high serum cholesterol. Discuss one mechanism by which fibers are proposed to lower serum cholesterol. (3 pts) Question 2Fructose intolerance is an inherited disorder in which a person is missing an enzyme called aldolase B, which is required to break down fructose. Without it, the person is not able to convert fructose to glucose and catabolize it. A) Name three (3) food groups or ingredients this person cannot eat? (3) B) How can the person get glucose in his/her diet for energy? (2) C) Write a one-day sample menu of for this person. (5) Question 3 a. Name the 4 sphincters and where they are located along the digestive tract (hint: the rectum is not one of them). (4 pts) b. Many hormones play a role in digestion. Name three (3) of them and state where they originate (0.5 pt each), whether they stimulate or inhibit digestion (0.5 pt each), name the organ they stimulate or inhibit (0.5 pt each), and the effect they have on digestion (0.5 pt each). (6 pts.) Question 4 Sam ate a plain bagel with jam for breakfast this morning State how the carbohydrates in this meal were digested, absorbed and cleared from his blood stream. (10 pts.)
Is the bоlded stаtement TRUE оr FALSE? Oxidаtive phоsphorylаtion describes a biological mechanism that takes place in virtually every eukaryotic organism cataloged. Predictions predicated upon the central components of this process can be tested using a model system in which intact mitochondria are isolated and brought to equilibrium. Given this experimental setup and a correct understanding of oxidative phosphorylation one would expect: 41. that additions of ADP and Pi would result in little to no ATP produced provided that a reduced electron carrier was absent. 42. that additions of ADP and Pi would result in ATP synthesis in all conditions so long as an uncoupler has been provided prior to the addition of ADP and Pi. 43. that inhibition of ATP synthesis, using oligomycin, would result in inhibition of the electron transport chain regardless of what had been added prior to or after the inhibition of ATP synthase. 44. that the addition of only DNP and succinate would result in oxygen consumption. 45. that the addition of only succinate to mitochondria that expresses a UCP (uncoupler protein), such as thermogenein, could result in oxygen consumption.
