Typical apples contain 84% water, 14% carbohydrates and 0.5% fat, a total of 98.5% content in the apple while the rest are possibly some fibers like the skin and solids that cannot be eaten such as seeds. To calculate the calorie content of the apple on the basis of 255 g, know first the weight of carbohydrates and fats in the apple and find their contribution to energy burned and water cannot be burned since it does not contain a carbon atom
Carbohydrate content : ((255 g*0.14)* 4 cal/g = 142.9 cal
Fat content : ((255 g*0.005)*9 cal/g = 11.475 cal
Total: 154.375 cal on a 255 g apple
The correct answer is actually
B. Glutamate
