"Consuming an entrée containing 700 kcalories, 30 grams of protein, 100 grams of carbohydrate, and 20 grams of fat would provide how many kcalories from protein?"

120 Kcal

Explanation:

The process of cellular respiration produces energy using the carbohydrate as substrate but it also uses proteins and fats as the substrate.

1 gram of fat provides- 9 kcal therefore 20 g of fat will provide

20x 9= 180 kcal.

1 gram of carbohydrate provides- 4 kcal therefore 100 g of carbohydrate will provide  

100 x 4 = 400 kcal.

1 gram of proteins provides-4 kcal therefore 20 g of protein will provide  

30 x 4=120 kcal.

Thus, in question proteins will provide 120 kcal.
