Title: Indirect calorimetry works based on the principle that ____. : Post by: kkhh on Mar 4, 2018 Indirect calorimetry works based on the principle that ____.
A) a rise in body temperature reflects the amount of energy expended B) the amount of heat produced is proportional to the energy expended C) oxygen consumption and carbon dioxide production are related to energy expenditure D) energy expenditure can be predicted if respiration and perspiration are carefully measured Q. 2 If creatine phosphate is nearly depleted in skeletal muscle by high-intensity exercise, approximately how long does it take to restore creatine phosphate levels? a. 1-2 seconds b. 1-2 minutes c. 1-2 hours d. 1-2 days Q. 3 Direct calorimetry works based on the principle that ____. A) a rise in body temperature reflects the amount of energy expended B) the amount of heat produced is proportional to the energy expended C) oxygen consumption and carbon dioxide production are related to energy expenditure D) energy expenditure can be predicted if respiration and perspiration are carefully measured Q. 4 If creatine phosphate is nearly depleted in skeletal muscle by high-intensity exercise, how is it rephosphorylated? a. By consuming creatine as a dietary supplement b. By consuming ATP as a dietary supplement c. From ATP generated anaerobically by glycolysis d. From ATP generated aerobically by oxidative phosphorylation Q. 5 On average, 1 liter of oxygen consumed is equivalent to ____ kcal of energy expended. A) 1 B) 3 C) 5 D) 7 Q. 6 What is the major factor that limits the use of the creatine phosphate energy system? a. The pH of the cell increases b. Creatine phosphate can be depleted c. Muscle glycogen can be depleted d. Increased oxygen consumption Q. 7 The energy content of ____ is estimated to be the same kcal/g. A) fats and proteins B) alcohol and fats C) carbohydrates and proteins D) carbohydrates and fats Q. 8 What is the effect on muscle ATP and creatine phosphate (CrP) when an athlete performs very-high-intensity exercise for a very short period of time (e.g., 10 seconds)? a. ATP and CrP both decline rapidly and in concert with each other. b. Neither ATP nor CrP decline much because of the very short duration of exercise. c. CrP declines rapidly but there is virtually no decline in ATP. d. ATP declines then plateaus while CrP declines substantially. Q. 9 6,300 kJ = ____ kilocalories. A) 630 B) 850 C) 1500 D) 3200 Title: Indirect calorimetry works based on the principle that ____. : Post by: subinbhusal2479 on Mar 4, 2018 C b B d C b C d C Title: Indirect calorimetry works based on the principle that ____. : Post by: kkhh on Mar 4, 2018 You are really a genius.
