LATEST BIOD 121 FINAL EXAM PRACTICE BANK:
QUESTIONS & ANSWERS WITH RATIONALES
Core Domains:
Macronutrients (Carbohydrates, Proteins, Lipids)
Micronutrients (Vitamins, Minerals, Water)
Digestion, Absorption, and Metabolism
Energy Balance, Caloric Calculations, and BMR
Nutrition Across the Lifespan (Pregnancy, Infancy, Childhood, Aging)
Nutritional Assessment (ABCDE Method)
Dietary Guidelines, DRIs, and MyPlate
Clinical Nutrition and Disease Prevention
This comprehensive practice bank is designed to prepare students for
the BIOD 121 Essentials in Nutrition Final Exam at Portage Learning.
The examination evaluates foundational knowledge in human nutrition,
including macronutrient metabolism, micronutrient functions, digestion
and absorption, energy balance, caloric calculations, and nutrition
across the lifespan . Questions are structured to assess both theoretical
understanding and practical application of nutrition science principles.
Each item includes a verified correct answer accompanied by a detailed
rationale to reinforce learning and support exam preparation for the
2026/2027 academic year.
SECTION ONE: QUESTIONS 1 – 100
Question 1
What is the difference between hunger and appetite?
A. Hunger is the internal drive to eat; appetite is the external drive that
encourages us to find food.
B. Hunger is the desire for specific foods; appetite is the sensation
,prompting eating.
C. Hunger is related to emotional states; appetite is influenced by the
food environment.
D. Hunger is only physiological; appetite is completely emotional.
A. Hunger is the internal drive to eat; appetite is the external drive
that encourages us to find food.
RATIONALE: Hunger is a physiological need for food driven by
internal signals, while appetite is a psychological desire to eat, often
influenced by external cues like sight, smell, and social settings.
Understanding this distinction is fundamental to nutritional counseling.
Question 2
A patient reports fatigue and pale skin. Laboratory results show low
hemoglobin and hematocrit levels. Which nutrient deficiency is most
likely responsible for these findings?
A. Protein
B. Iron
C. Vitamin B12
D. Folate
B. Iron
RATIONALE: Fatigue, pale skin, and low hemoglobin/hematocrit
are classic signs of iron deficiency anemia. Iron is essential for
hemoglobin synthesis, which carries oxygen to tissues. Vitamin B12 and
folate deficiencies also cause anemia but typically present with
macrocytic (large) red blood cells.
Question 3
,The ABCDEs of nutritional assessment stand for:
A. Anthropometric, Biochemical, Clinical, Dietary, Environmental
B. Activity, Biochemical, Clinical, Dietary, Exercise
C. Anthropometric, Biological, Clinical, Dietary, Emotional
D. Activity, Biological, Clinical, Dietary, Environmental
A. Anthropometric, Biochemical, Clinical, Dietary, Environmental
RATIONALE: The ABCDE acronym is the standard framework for
nutritional assessment. Anthropometric measures include height, weight,
and BMI. Biochemical tests evaluate blood and urine markers. Clinical
assessment involves physical examination. Dietary assessment reviews
food intake. Environmental considers socioeconomic and lifestyle
factors.
Question 4
Which of the following best defines malnutrition?
A. Only a deficiency of calories
B. Only an excess of calories
C. A deficiency, excess, or imbalance of nutrients
D. A lack of appetite
C. A deficiency, excess, or imbalance of nutrients
RATIONALE: Malnutrition encompasses both undernutrition
(deficiencies) and overnutrition (excesses). It refers to any imbalance in
nutrient intake that leads to adverse health effects. This broad definition
is important for understanding global nutrition challenges.
Question 5
, What is the primary difference between a macronutrient and a
micronutrient?
A. Macronutrients provide energy; micronutrients do not.
B. Macronutrients are organic; micronutrients are inorganic.
C. Macronutrients are required in larger amounts; micronutrients in
smaller amounts.
D. Both A and C are correct.
D. Both A and C are correct.
RATIONALE: Macronutrients (carbohydrates, proteins, fats)
provide energy and are needed in gram quantities daily. Micronutrients
(vitamins, minerals) do not provide energy but are essential for
metabolic processes and are needed in milligram or microgram
quantities.
Question 6
A triglyceride is a polymer made up of which kind of subunits?
A. Amino acids
B. Nucleotides
C. Simple sugars
D. Fatty acids and glycerol
D. Fatty acids and glycerol
RATIONALE: A triglyceride is a type of lipid composed of a
glycerol backbone attached to three fatty acid chains. Amino acids make
up proteins, nucleotides make up nucleic acids, and simple sugars make
up polysaccharides.
