Scientists and nutritionists have long suspected that high-fructose corn syrup, used to sweeten soft drinks, is one of the causes of childhood obesity. In a recent study, at the University of Cincinnati, researchers found that mice that drank water with added fructose ate less solid food, gained more weight, and put on 90% more body fat than mice that drank only water. Scientists concluded that fructose may cause the body to store fat. What is the control used in this experiment?

You have the task of producing 3 kilogram of porcine (pig) insulin from pig pancreases to create an emergency stockpile of insulin. You know that a typical adult pig has a 269 gram pancreas and it is possible to produce 15 micromoles of purified insulin from 1 kg of pancreatic tissue. How many fresh pig carcasses would you need to produce 3 kg of insulin?

1) Discuss recent findings on the effects of consumption of cholesterol and saturated, polyunsaturated, and monounsaturated fats. Give examples of each type of fat. 2) We often think only of DNA and RNA as nucleic acids. Discuss the role of other, less “well-known” nucleic acids, such as cAMP, cGMP, NADH, NADPH, and FADH. 3) Collagen is a very important structural protein in animals. Discuss the various parts of the body in which collagen is an important structural molecule and what its function is at each body location.
On the right is a diagram of plasma concentration of three metabolites: glucose, B- hydroxybutyrate, and free fatty acid of an experimental animal over weeks of starvation. 4. (a) Label the lines with the names of the three metabolites. Yellow: Red: 10 20 30 40 Blue: Days of starvation (b) What factor in the plasma binds to and transports free fatty acid (c) Where was B-hydroxybutyrate produced? Why it is produced? What are the purposes of producing it (d) How B-hydroxybutyrate is used as fuel in extrahepatic cells? Write down the reactions, enzymes, and cofactors (No need to elaborate on the TCA cycle). (e) How many ATP molecules or equivalent are generated after complete oxidation of one molecule of B-hydroxybutyrate? Show your calculations. Hint: You need to consider ATP consumption for bypassed steps that may normally yield or consume AT Plasma concentration (mM)
Many people who are lactose intolerant can eat yogurt, which is prepared from milk curdled by bacteria, without any digestive problems. Give a reason why this is possible. (Hint: Read the label on each of several yogurt containers. Do the ingredients make a difference?)
Look at the nutrition labels for a Blueberry Nutrigrain Bar and a Blueberry RX Bar, also paying close attention to the ingredient lists provided in each. Answer the following questions: What is the difference between total sugars and added sugars? How do the total sugars and added sugars differ in these two bars? What are the biggest differences in the ingredient lists in these bars? Choose one ingredient that you have not heard of from the list from either bar. Explain to the class what the ingredient is and what its purpose is.
(AKS 8a, DOK 2) Students in biology classes at MHS have been conducting an experiment that invloves producing bacteria that produce human insulin. In essence, students are placing an insulin gene from the human pancreas into the bacterial genome. This was done to produce genetically engineered bacteria that make a human protein. Which question addresses the ethical concerns regarding this biotechnological method? A. Will the insulin produced by the bacteria be réadily used by humans? B. Will the insulin produced by genetically altered bacteria increase the chances of individuals becoming ill? C. Will the bacteria become part of the human genome after the addition of the insulin gene? D. Will the insulin produced by genetically altered bacteria be viewed by different religious groups needing to be treated for diabetes? Ce
According to current dietary recommendations, trans fat intake should be limited. How is this best accomplished? Group of answer choices Select foods containing manufactured rather than naturally occurring trans fats. Read labels to select foods that say “polyunsaturated fatty acid free.” Choose foods with <10% of calories from saturated fat per serving and no hydrogenated oils in the ingredients list. Use fat replacers, such as olestra, which provide the same nutrient content as regular fats without being saturated. Avoid all processed foods such as bakery items, packaged cookies, and store-bought bread.
"Dietary restriction has been shown to have several health benefits including increased insulin sensitivity, stress resistance, reduced morbidity, and increased life span. The mechanism remains unknown, but the need for a long-term reduction in caloric intake to achieve these benefits has been assumed. We report that when C57BL6 mice are maintained on an intermittent fasting (alternate-day fasting) dietary-restriction regimen their overall food intake is not decreased and their body weight is maintained. Nevertheless, intermittent fasting resulted in beneficial effects that met or exceeded those of caloric restriction including reduced serum glucose and insulin levels and increased resistance of neurons in the brain to excitotoxic stress. Intermittent fasting therefore has beneficial effects on glucose regulation and neuronal resistance to injury in these mice that are independent of caloric intake".
