Igcse Model Questions Vol1 2025 Biology Question 15
Practice objective / multiple choice question 15 from the 2025 Igcse Model Questions Vol1 Biology examination.
A diet provides \(2500\ \text{kcal}\) per day. Carbohydrates supply 55 % of the energy, proteins 15 % and fats the remainder. Only 90 % of the carbohydrate energy, 95 % of the protein energy and 98 % of the fat energy are absorbed. (a) Calculate the net energy actually available to the body from this diet (in kcal, to one decimal place). (b) If the person replaces 250 kcal of carbohydrate energy with an equal amount of fat energy (so total intake remains 2500 kcal), recalculate the net available energy. Give both answers to one decimal place.
