Question

The energy content in Kcal/g of carbohydrate : protein : triglycerol respectively is approximately in the ratio of

• A. 1 : 2 : 2
• B. 1 : 1 : 2
• C. 2 : 1 : 1
• D. 2 : 2 : 1

Answer 1

Answer: (B)

1 : 1 : 2

The energy content in Kcal/g of carbohydrate = 4. The energy content in Kcal/g of proteins = 4. The energy content in Kcal/g of triglyceride = 8.
The ratio is thus: 4 : 4 : 8 = 2 : 2 : 4 = 1 : 1 : 2.

So, the correct answer is option B.
