Anna tries to keep her kilocalorie intake under control. She eats mostly lean meats or fish and a lot of vegetables. Yesterday,

for dinner, she had 3 ounces of baked salmon with half a cup of mashed sweet potatoes and about a cup of steamed asparagus. She is concerned about her weight and decided to calculate the kilocalories in her meal. She looked up the nutrient content of her foods and she consumed 7 grams of fat (in salmon) 36 grams of carbohydrates (in sweet potatoes and asparagus) 27 grams of protein (in salmon, sweet potatoes, and asparagus) Part A Energy Value of a Meal How many kilocalories did Anna consume for dinner? Round the number of kilocalories to the nearest whole number. View Available Hint(s) kilocalories Submit Part B - Energy Value of a Macronutrient How many of Anna's kilocalories came from proteins? Round the number of kilocalories to the nearest whole number. View Available Hint(s) kilocalories

Answer:

A.- 300kcal (315kcal) / B.- 100kcal (108kcal) - arround (30-35%)

Explanation:

In order to determine how many kilocalories have the meal, you have to multiply the macro-molecule grams as the following rule:

lipids * 9 / carbohydrates * 4 / proteins * 4

then

7g*9 + 36g*4 + 27g*4 = 63kcal + 144kcal + 108kcal (P) = 315kcal

Answer:

A). 315 Kcal

B). 108 KCal

Explanation:

The reason we eat is to obtain energy, which is the same reason Anna ate dinner yesterday. Food consists of different classes but the three major ones that acts as sources of energy are Carbohydrates, fats and protein. The energy in the food we ingest is measured in Kilocalories (Kcal) which is a thousand calories.

However, the different classes of food mentioned above contains different quantities of energy per gram i.e.

1 gram of carbohydrate = 4 Kcal

1 gram of protein= 4 Kcal

1 gram of fat = 9 Kcal

Hence, to calculate the total energy value (Kcal) present in the dinner Anne ate, we multipy the grams of each class of food by it's corresponding energy value in Kcal. Thus, we have;

For 7 grams of fat, 7 × 9 Kcal/g = 63 Kcal

For 36 grams of carbohydrates, 36 × 4 Kcal/g = 144 Kcal

For 27 grams of protein, 27 × 4 Kcal/g = 108 Kcal

Hence, the total energy value contained in the food is:

63 + 108 + 144

= 315 Kcal

For question B, based on the above explanation, 27 grams of protein was present in the food eaten. Hence, 27 × 4 Kcal/g = 108 Kcal

108 Kcal of protein contributed to Anna's total Kcal present in the food.

agasfer [191]

Answer:

Productivity is refers to the rate of generation of biomass in an ecosystem. The difference between net and gross productivity is that gross productivity is    is the overall rate of energy capture while net productivity is  is lower, adjusted for energy used by organisms in respiration/metabolism.
