A woman consumes 500 grams of carbohydrate, 30 grams of protein, and 75 grams of fat in one day. How many total kcalories has she taken in, and how many and what percentage of kcalories are from carbohydrate, protein, and fat? A. Total kcalories:
B. Percentage of kcalories from carbohydrate:
C. Percentage of kcalories from protein:
D. Percentage of kcalories from fat:

Answer and Explanation:

The computation is shown below:

A. For Total k. calories

= (Number of grams in carbohydrates × 1 gm of carbohydrates) + (Number of grams in protein × 1 gm of proteins) + (number of grams in fat × 1 gm in fat)

= (500 × 4) + (30 × 4) + (75 × 9)

= 2000 + 120 + 675

= 2795 k. calories

b. As we know that

1 gm of carbohydrates = 4 k. calories

So, for 500 grams it would be

= 500 × 4

= 2000 k. calories

Now the percentage is  

= Total grams in carbohydrates ÷ Total kcalories

= 2000 ÷ 2795

= 0.72

= 72%

C.  As we know that

1 gm of proteins = 4 k. calories

So, for 40 grams, it would be

30 × 4 = 120 k. calories

Now the percentage is

= Total grams in protein ÷ Total kcalories

= 120 ÷ 2795

= 0.043

= 4.3%

D. As we know that

1 gm of fat = 9 k. calories

So for 75 grams, it would be  

75 × 4 = 200 k. calories

So, the percentage is

= Total grams in fat ÷ Total kcalories

= 200 ÷ 2795

= 0.072

= 7.2%

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
