Questions Energy Expenditure Themes

14. BMR Which statement regarding Basal Metabolic Rate (BMR) is CORRECT? A.Whole body BMR is generally lower in people who weigh more B.BMR contributes more to whole body energy expenditure than diet induced thermogenesis C.BMR is assessed by comparing food intake to weight gain D.BMR is inversely proportional to lean body mass E.Thyroid hormone lowers BMR goes up with weight yes, 60% of daily EE no, calorimetry directly! they increase BMR!

15. Fuel Stores Which statement is CORRECT? A.Brain can use fatty acids B.Fatty acids can be converted into glucose C.Muscle glycogen is the major carbohydrate reserve for the brain D.The total amount of glycogen stored in muscle is less than the total amount stored in liver E.There is no specific protein that represents a store of amino acids big NO!!! although lots of glycogen in muscle, can’t access no 250g vs 100g a true negative statement!!

16. Measuring Metabolic Rate Both indirect calorimetry and the doubly-labeled water (D2O18) methods can be used to assess whole body energy expenditure. Which statement is CORRECT? A.Only indirect calorimetry can give an indication of which fuels are being burnt B.The doubly-labeled water method measures oxygen production C.The doubly labeled water method can be done over a shorter time frame than indirect calorimetry D.Only the doubly labeled water method can be used to determine basal metabolic rate E.Indirect calorimetry only works if the subject has consumed carbohydrates, not fat. yes. RQ carbs is 1, fat is 0.7 no, carbon dioxide no, much longer no, multicomponent a silly statement!

17. Leptin Which of the following statements regarding leptin is CORRECT? A.Leptin is secreted by the β-cells of the pancreas in response to a carbohydrate meal B.Obese subjects have a lower blood leptin concentration than non-obese subjects C.Obese subjects are hyper-responsive to leptin D.A lack of leptin will cause ravenous hunger E.In rodents, leptin inhibits thermogenesis in brown adipose tissue no, by WAT no, much higher no, resistant absolutely stimulates energy expenditure
