Question

A nutrition facts label can be found on the packaging of most food items. The label describes the nutritional composition of the food. In the United States, federal law requires that the amounts of certain nutrients be given, though manufacturers sometimes add additional information.
Consider the following minimal nutrition facts label describing the nutritional composition of oranges.

Nutrition Facts for One Medium Orange (131 g)
Calories 72 Calories from Fat 0
% Daily Value*
Total Fat 0 g 0%
Saturated Fat 0 g 0%
Cholesterol 0 mg 0%
Sodium 1 mg 0%
Total Carbohydrate 17 g 6%
Fiber 3 g 12%
Sugars 10 g
Protein 1 g
Vitamin A 7% Vitamin C 130%
Calcium 5% Iron 1%
* Percent Daily Values are calculated based on a 2,000 calorie diet.

Based on the label, is this food:
(A) a source of amino acids?
(B) a source of fatty acids?
(C) a source of fuel molecules that supply energy?

Based on the label, _______ is the most abundant macronutrient in oranges.

Answer 1

Answer:

1. Yes ;as evident from option (C); a source of fuel molecules that supply energy).The Nutritional value  of orange contains 10g of sugars as;( glucose, fructose, and sucrose) out of the total 17g carbohydrate.Therefore  the sugars are substrates(as glucose) in cellular respiration for ATPs synthesis, .

2.Based on the label, Carbohydrate 17 g 6% is the most abundant macro nutrient in oranges. The nutrients needed in large amounts in the body for supply of large calories and maintenance of  normal physiological functions, and structures.  are called Macro-nutrients. Seven major macro nutrients are available from diets. But Carbohydrates, Proteins, and Fats are the most common and important.

In contrast Micronutrients are needed in small amount in organisms just for the well being .They do not supply energy but maintain  body metabolic reactions. Minerals, K, Na, Mg and Vitamins A, B12,C are example of micro nutrients
