Can you explain the answer of this question below:The energy content in kcal/g of carbohydrate:protein:triglycerol is approximately in the ratio ofA:1:2:1B:2:2:1C:1:1:2D:1:2:2The answer is c.

Question

Answer

Carbohydrates supply energy at the physiological rate of 4 kcal/g (caloric value 4.1), fats are the source of energy with a physiological rate of 9 kcal/g (caloric value 9.45), while proteins may yield energy at 4.65 kcal/g caloric value or 4.0 kcal/g physiological fuel value.

Answer

Ratio of Energy Content in Carbohydrate, Protein and Tri-glycerol

Carbohydrates, proteins and tri-glycerol are three main macronutrients that provide energy to the body. The energy content in kcal/g of these macronutrients is given below:

- Carbohydrate: 4 kcal/g
- Protein: 4 kcal/g
- Tri-glycerol (fat): 9 kcal/g

The ratio of energy content in kcal/g of carbohydrate, protein and tri-glycerol can be calculated as follows:

- Carbohydrate: 4 kcal/g
- Protein: 4 kcal/g x 1 = 4 kcal/g
- Tri-glycerol: 9 kcal/g x 2 = 18 kcal/g

Therefore, the ratio of energy content in kcal/g of carbohydrate : protein : tri-glycerol is approximately 1:1:2. Hence, option C is the correct answer.

Answer

Calories are needed to provide energy so, the body functions properly. The number of calories in a food depends on the amount of energy the food provides. The number of calories a person needs depends on age, height, weight, gender and activity level. People who consume more calories than they bum off in normal daily activity or during exercise are more likely to be overweight. Fat (1 gram) = 9 calories Protein (1 gram) = 4 calories Carbohydrates (1 gram) = 4 calories Triglycerol is an ester derived from glycerol and three fatty acids. It is the main constituent of vegetable oil and animal fats. Therefore, the approximate ratio of the energy content in kcal/g of carbohydrate: protein : triglycerol is 1 : 1 : 2.

Answer

Yes, correct answer is C because by carbohydrate(approx 4.0kcal/gram):protein(4.5kcal/gram): fat(9.0 kcal/gram) so approximately ratio of energy is (1:1:2)

C
