A slice of apple pie contains 14.0 grams of fat, 2.00 grams of protein, and 52.0 grams of carbohydrate. The respective fuel values for protein, fat, and carbohydrate are 17, 38, and 17 kJ/g, respectively. If cycling typically burns 1000.0 kJ/hour, __________ minutes of cycling are required to completely burn off the slice of pie.

Question

Quizplus · Accepted Answer

To find the total energy content of the slice of pie, calculate the energy from each macronutrient:  - Fat: 14.0 g × 38 kJ/g = 532 kJ  - Protein: 2.00 g × 17 kJ/g = 34 kJ  - Carbohydrate: 52.0 g × 17 kJ/g = 884 kJ  Total energy = 532 + 34 + 884 = 1450 kJ  Since cycling burns 1000 kJ/hour, the time required to burn 1450 kJ is (1450 kJ / 1000 kJ/hour) × 60 minutes/hour = 87.0 minutes.
