Question

A person eats 8 grams ofprotein, 25 grams ofcarbohydrates, 6 grams offat and 4 grams of alcohol.What is the total energyvalue (in calories) fromthese stated amounts?a. 204 kCaloriesb. 254 kCaloriesc. 214 kCaloriesd. 244 kCaloriese. 224 kCalories

Answer 1

Answer:

C) 214 kCalories

Explanation:

The human body requires energy to perform various functions in the cell which they get from the food product we eat.

The digestion of food material by the process of cellular respiration provides energy in the form of ATP. The number of ATP production depends on the type of molecule used as a substrate during respiration. The formation of ATP is converted in the SI unit calorie by the scientists to make an easy understanding of the layman.

• The oxidation of 1 g of protein gives 4 kcal, therefore, the 8 gm will produce 32 kcal
• The oxidation of 1 g carbohydrate provides 4 kcal therefore 25 g will provide 100 kcal  
• The oxidation of 1 g fat provides 9 kcal therefore 6 g of fat will provide 54 kcal
• The oxidation of 1 g of alcohol provides 7 kcal therefore 4 g of alcohol will provide 28 kcal.
• The total calories from the food containing these ingredients will be- 32+ 100+ 54+ 28= 214 kcal.

Thus, Option-C is the correct answer.
