After strenuous exercise, you may notice that your muscles burn and feel sore the next day. Which statement best explains this phenomenon? (a) Proteins in muscle cells are being digested to provide energy. (b) Carbon dioxide is building up in muscle cells and changing their pH. (c) Spontaneous combustion occurs during strenuous exercise, so avoid it at all costs! (d) ATP is accumulating in muscle cells, causing a burning sensation. (e) Without adequate oxygen, muscle cells are fermenting pyruvate into lactic acid.
I played field hockey for 1 hour and my Fitbit Watch says that I expended 1,085 Calories. If triglycerides in my adipose (fat) cells powered all that activity, how may grams of fat were consumed in powering that exercise? (Hint: the Calorie Content of Fats you determined in Lab Exercise 9A was 8.9 Calories/g): Show your calculation…

- Select the best answer or answers from the choices given: The net gain of ATP from the complete metabolism (aerobic) of glucose is closest to (a) 2, (b) 30, (c) 3, (d) 4.arrow_forwardWhich of the following statements is not true? (a) Glycolysis is the first stage of cellular respiration. (b) Glycolysis can proceed under low oxygen levels with the assistance of fermentation. (c) Glycolysis produces less ATP than does either the Krebs cycle or oxidative phosphorylation. (d) Glycolysis produces most of the ATP required by aerobic organisms like us.arrow_forwardSince ancient times it has been observed that certain game birds, such as grouse, quail, and pheasants, are easily fatigued. The Greek historian Xenophon wrote: “The bustards . . . can be caught if one is quick in starting them up, for they will fly only a short distance, like partridges, and soon tire; and their flesh is delicious.” The flight muscles of game birds rely almost entirely on the use of glucose 1-phosphate for energy, in the form of ATP . The glucose 1-phosphate is formed by the breakdown of stored muscle glycogen, catalyzed by the enzyme glycogen phosphorylase. The rate of ATP production is limited by the rate at which glycogen can be broken down. During a “panic flight,” the game bird’s rate ofglycogen breakdown is quite high, approximately 120 mmol/min of glucose 1-phosphate produced per gram of fresh tissue. Given that the flight muscles usually contain about 0.35% glycogen by weight, calculate how long a game bird can fly. (Assume the average molecular weight of a…arrow_forward
- After prolonged exercise the body becomes depleted of glycogen. Which type of diet will lead to a quicker replenishment of muscle glycogen, a high fat, high protein diet or a high carbohydrate diet?Explain.arrow_forwardAfter the lunch meal, a student felt that the digestion didn't go well. He decided to take some digestive enzyme tablet that helped the digestion. In Michaelis-Menten Equation, which term will be affected? 1.[S] 2. [E]o 3. Kcat ○ 4.Km 05.[1]arrow_forwardWhat percentage of ATP is derived from fat versus carbohydrate when your participant is exercising at a respiratory exchange ratio (RER) of 0.90? Equation: [(1 - RER)/0.3] * 100 = Percent energy from FAT 100 - FAT = Percent energy from CHOarrow_forward
- The Liver makes “Ketone Bodies” (acetoacetic acid and -hydroxybutryic acid): a. as a long-term energy storage reserve b. to provide an alternative energy source to muscle, the kidney and other organs when on a prolonged low carbohydrate diet c. from fatty acids oxidized to acetyl CoA d. to detoxify lactose absorbed from the large intestine e. when our muscles cannot get enough oxygen to carry out oxidative phosphorylationarrow_forwardMarathon runners often practice "carb loading" prior to a race. The purpose of this practice is to increase the stores of energy available for muscles to use. Explain how energy is used by muscle fibers and how this practice of "card loading" benefits the runner's muscles. Be sure to use the terms glucose, glycogen, creatine, phosphate, and ATP in the explanation.arrow_forwardThe requirement of calories for healthy adults per day is() A) 10~15 kcal/kg body weight B) 15~20 kcal/kg body weight C) 20~25 kcal/kg body weight D) 25~30 kcal/kg body weight E) 30~35 kcal/kg body weightarrow_forward
