QUESTION:
Using the energy values for foods (see Table 2.9), determine each of the following (round off the answers for kilojoules and kilocalories to the tens place):a. the kilojoules for 1 cup of orange juice that contains 26 g of carbohydrate, no fat, and 2 g of proteinb. the grams of carbohydrate in one apple if the apple has no fat and no protein and provides 72 kcal of energyc. the kilocalories in 1 tablespoon of vegetable oil, which contains 14 g of fat and no carbohydrate or proteind. the kilocalories for a diet that consists of 68 g of carbohydrate, 9.0 g of fat, and 150 g of proteinTABLE 2.9 Typical Energy (caloric) Values for the Three Food TypesFood TypeKJ/gKcal/gCarbohydrate174Fat389Protein174
ANSWER:Solution 41QPStep 1 of 6:The goal of the problem is to determine the energy for given criteria. Given: The caloric content of food type is shown in the table below:Food TypekJ/gkcal/gCarbohydrate174Fat389Protein174The total energy of a food, when the mass of each food type is known can be calculated as below: and ________________a. Given:Mass of carbohydrate = 26 g.Mass of fat = 0 gMass of protein = 2 g Energy in kilojoules =Let’s find the energy of carbohydrate:The caloric content of carbohydrate (in kJ) = 17 kJ/g. = 26 g = 442 kJ. Mass of Fat is 0 g, so it is not calculated.Let’s find the energy of protein:The caloric content of protein (in kJ) = 17 kJ/g. = 2 g = 34 kJ. ________________
