Final answer:
Caloric contributions in the turkey drumstick are calculated by multiplying grams of each nutrient by their respective calorie values per gram, with fat at 9 calories/g and protein at 4 calories/g. This yields 119.7 calories from fat and 279.2 calories from protein, leading to percentages of 28.8% and 67.1% respectively of the total 416 calories.
Step-by-step explanation:
Calculating Nutritional Value and Caloric Percentages
To calculate the calories derived from each nutrient in a turkey drumstick, use the facts given about proteins, carbohydrates, and fats, understanding that proteins and carbohydrates each provide 4 calories per gram and fats provide 9 calories per gram. Given the composition of the drumstick, the calories from fat are calculated as 13.3g times 9 calories/g, equaling 119.7 calories. The calories from proteins are 69.8g times 4 calories/g, equaling 279.2 calories. Since there are zero carbohydrates, they contribute zero calories. Thus, the sum of the calories (119.7 from fat and 279.2 from protein) gives us a total of 398.9 calories, which is slightly less than the total calories stated (416), suggesting there may be minor components like alcohol or organic acids or rounding in label values affecting the total number.
To determine the percentage of each nutrient's caloric contribution, divide the calculated calories for each nutrient by the total calories and multiply by 100. Therefore, fat provides (119.7/416)*100% = 28.8% of the calories, and protein provides (279.2/416)*100% = 67.1% (recognizing that percentages might not total 100% due to rounding or other minor caloric components).
