Answer:

The 200 grams of carbohydrate would this convert to 800 kcals in a day.

Explanation:

Carbohydrates are the source of energy. The metabolism of 1 gram of carbohydrates gives 4 kcals of energy.

If 200 grams of carbohydrate is consumed in a day, then the energy provided by it is:-

$Energy\ provided\ by\ the\ carbohydrate = 200\times 4\ kcals=800\ kcals$

<u>The 200 grams of carbohydrate would this convert to 800 kcals in a day.</u>
