Gce Model Questions Vol1 2017 Biology Question 9
Practice objective / multiple choice question 9 from the 2017 Gce Model Questions Vol1 Biology examination.
A meal contains 30 g protein, 50 g carbohydrate and 20 g fat. The digestibility of protein, carbohydrate and fat are 80%, 90% and 95% respectively. The carbohydrate portion also contains 5 g of fibre which reduces the net carbohydrate absorption by 5% of the total carbohydrate amount. Using the Atwater factors (protein 4 kcal·g\(^{-1}\), carbohydrate 4 kcal·g\(^{-1}\), fat 9 kcal·g\(^{-1}\)), calculate the metabolizable energy supplied by the meal (in kcal, to the nearest whole number).
