How to Use This Guide
Read each stem, select your answer, then review the rationale. Correct answers are distributed
across all four letter positions. Covers micronutrients, digestion, blood glucose, proteins, lipids,
BMR, BMI, behavior modification, vitamins, minerals, iron absorption, life cycle nutrition, eating
disorders, and aging for the BIOD 121 Final Exam.
Questions 1–55: Micronutrients, Digestion, Energy Balance & Life Cycle
1 List 2 micronutrients and provide a function of at least 1.
A Vitamins (regulate body processes) and Minerals (structure, regulate body
processes)
B Carbohydrates (energy) and Proteins (structure)
C Fats (energy) and Water (hydration)
D Fiber (digestion) and Starch (energy)
Correct Answer: A. The two micronutrient classes are vitamins (organic, regulate
body processes) and minerals (inorganic, provide structure and regulate
processes). Both are needed in small amounts.
Rationale: B, C, D list macronutrients or carbohydrate subtypes. Micronutrients
are distinguished by the small quantities required and their regulatory/structural
roles.
, 2 A fudge brownie has 13g carbs, 1g protein, and 11g fat. How many
calories?
A 155 calories
B 135 calories
C 175 calories
D 125 calories
Correct Answer: A. Carbs: 13 × 4 = 52. Protein: 1 × 4 = 4. Fat: 11 × 9 = 99. Total:
52 + 4 + 99 = 155 calories. The 4-4-9 rule is essential for all nutrition calculations.
Rationale: B, C, D result from arithmetic errors. Always multiply carbs/protein by 4
and fat by 9 when calculating total calories from macronutrient grams.
3 You should not consume more than 45% of 2000 calories from
carbohydrates. How many grams?
A 225 grams
B 90 grams
C 450 grams
D 180 grams
Correct Answer: A. 2000 × 0.45 = 900 calories. 900 ÷ 4 kcal/g = 225 grams of
carbohydrates. This demonstrates the 4-4-9 rule for converting between calories
and grams.
Rationale: B is the calorie amount divided by 10. C is the calorie amount. D is
incorrect. Remember to divide carb calories by 4 to convert to grams.
