You have a friend who became stranded in a blizzard without food for severalweeks. This friend, when rescued, had lost about 7 kg (about 15 Ibs). As hewas quite healthy to begin with, he assumed the weight he lost was stored fat,but he wondered where the fat had gone, How did the fat leave his body?a. It was converted to heat and then released.b. It was converted to ATP, which weighs much less than fat.c. It was released as CO2 (as he was breathing) and some as H20.d. It was broken down into animo acids and eliminated through the body.e. It was converted to urine and eliminated from the body.

For doing any physical activities by person they need energy and those energy comes from The…

He reasons that a liter (about a quart) of water weighs 1000 g, whichis equivalent to 580,000 cal, or 580 kcal, of heat when lost as sweat.Therefore, instead of reducing his diet by 580 kcal/day, he believesthat losing a liter of sweat every day in the sauna will cause him tolose about a pound of fat a week. Will this approach work? Explain.
Energy from the breakdown of ATP provides the kinetic energy formuscle movement. Why does body temperature increase duringexercise?
Through anaerobic repsiration, cellular pyruvic acid is converted to? A. Lactic acid B. Glucose C. ATP D. Fatty acids
In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.

In the 1930's a chemical known as DNP was touted as en effective diet pill. Weight loss was dramatic in patients taking this drug. However, to quote Efraim Racker (A New Look at Mechanisms in Bioenergetics, Academic Press, 1976, p. 155), ..."the treatment eliminated not only the fat but also the patients,... This discouraged physicians for awhile..." This drug promotes weight loss by causing the leakage of H* across the inner mitochondrial membrane. Which of the following would you expect to see in patients taking DNP? [Select the best answer.] decreased ability to produce ATP increased ability to produce ATP decreased ability to use the Citric Acid Cycle to produce ATP slowing down the Citric Acid Cycle.

After a meal that contains carbohydrates, blood glucose levels usually rise gradually as carbohydrates are digested and the resulting monosaccharides are absorbed into the bloodstream. Suppose you run a test on a human with no lactase production. You would provide a dose (e.g., 25 grams) of lactose and measure changes in blood glucose levels over the next three hours. Predict how blood glucose levels would change from fasting to three hours. Justify your response using the results from the above simulation.

Which of the following statements is/are FALSE about glycolysis? A. It is an anaerobic process. B. Some steps occur in cytosol, others in mitochondria. C. It is the conversion of glucose to lactate or ethanol. D. It is the 1st stage of glucose metabolism.
Muscle soreness and fatigue in a racehorse after a long, strenuous race is a result of in the muscle. A. anaerobic metabolism, which leads to lactic acid buildup B. aerobic metabolism, which leads to buildup of carbon dioxide C. aerobic metabolism, which leads to lactic acid deficiency D. anaerobic metabolism, which leads to ATP buildup
