Lassieâs resting metabolic rate was determined to be 358 mL min-1 with a respiratory exchange ratio of 0.77, with light exercise (walking) Lassieâs metabolic rate increased to 662 mL min-1 with a respiratory exchange ratio of 0.83, and for a brief period of time, Lassieâs metabolic rate was maximal at 3550 mL min-1 with a respiratory exchange ratio of 1.36 while he was running up a steep gradient. How much CO2 was Lassie excreting at each of these three time points? Consider one day (24 hours) in which 60% of the time Lassie was at his basal (resting) metabolic rate, 39% of his time was at light exercise (662 mL min-1) and the remaining 1% of his time was at maximal exertion (3550 mL min-1). Assuming Lassieâs been eating a dogfood diet composed of 45% protein, 30% fat, and 25% carbohydrates, how much energy did he expend in that day?
