Homework Answers
Answer: When a person has not eaten for several hours.
( When there is no energy for the body, the body starts to burn fats for providing fuel energy to the body. Hence the fat is used for providing energy. After several days on starvation, the body utilizes protein for the energy)

From the information in Chapter 8 on metabolism and Appendix A, we can see the multiple metabolic pathways involved in generating ATP from the breakdown of the nutrients glucose, protein and fats. Glycolysis generates pyruvate, the pyruvate then becomes Acetyl CoA, which enters the Krebs Cycle (TCA), products of the Krebs Cycle then enter the Electron Transport Chain (ETC) where ATP is the final product. Fat breakdown (beta-oxidation) also generates Acetyl CoA, which then enters the Krebs Cycle to produce...

Le past years Question 42 O pts Extra Credit. Which of the following explains why low-fat diets are not necessarily the best for all humans? Individual humans have varying metabolisms and set points" When we eat less that - 20% of our calories from fat, we make fat from carbohydrates anyway We synthesize most of the cholesterol we use in our bodies regardless of diet Promoting low or no-fat diets in the past has caused many humans to over-consulte carbohydrates,...

26. Why did Jessie’s carnitine deficiency cause her to have abnormally low plasma glucose levels at the end of a fasting study, when compared to a healthy person who has fasted for the same length of time? In the absence of carnitine, the liver stores large amounts of glycogen; absorption of glucose to create these stores depletes blood glucose Carnitine acts as a hormone and stimulates glucose release from the liver; lack of carnitine results in loss of hepatic glucose...

Metabolism and Body Composition: Amanda and Becky are both high school seniors (18-year-old females) who are trying to improve their health and lose weight before graduation. Amanda decides to try the "Hollywood cleanse," in which she onl;y consumes fruit juice prepared from concentrate during the last four weeks of school. The cleanse provides 1000 kcal/day. Becky decides to go even further and drink only water during this time (no food or calorie-containing beverages). Measurements and lab values are shown below...
