5. Which of the following is the most accurate statement regarding the functions of protein?
a. Proteins can be a primary fuel source even if there is adequate carbohydrate intake.
b. Proteins are a necessary nutrient to provide energy for the body in times of stress.
c. Proteins can be used as coenzyme factors during cell metabolism.

6. A 65-year-old man requires 2000 kcal/day without any specific fat or carbohydrate
requirements. The approximate number of kilocalories per day from fat his diet should provide is
kcal/day.
a. 400 to 700
b. 100 to 300
c. 500 to 800
d. 900 to 1200
ANS: A
Fat should provide no more than 20% to 35% of the total kilocalories per day, so for a 2000-kcal
diet 400 to 700 kcal should be provided.

8. The number of kilocalories provided by one slice of bread that contains 30 g carbohydrate, 3 g
protein, and 1 g fat is kcal.
a. 34
b. 136
c. 141
d. 306
,ANS: C
Calculate as follows: Carbohydrate provides 4 kcal/g, protein provides 4 kcal/g, and fat provides
9 kcal/g. Therefore:
30 g carbohydrate 4 kcal/g = 120 kcal
3 g protein 4 kcal/g = 12 kcal
1 g fat 9 kcal/g = 9 kcal
= 141 total kcal (120 kcal + 12 kcal + 9 kcal)
