Free ACBN Nutritionist Trivia Questions and Answers — Questions and Answers
Question 1: BCAAs are a necessary amino acid and are crucial for energy during exercise.
- Dermis
- Hypodermis
- Tryptophan
- Pepsin (Correct answer)
Correct answer: Pepsin
The question as written is problematic, as BCAAs are amino acids, not Pepsin. However, assuming the question implicitly asks about an enzyme involved in protein digestion among the choices, Pepsin is the correct answer. Pepsin is a proteolytic enzyme released in the stomach that initiates protein digestion by breaking down proteins into smaller polypeptides.
Question 2: An enzyme that digests proteins into smaller peptides and free amino acids is released in the stomach.
- Pepsin (Correct answer)
- Hypodermis
- Dermis
- Tryptophan
Correct answer: Pepsin
Pepsin is a crucial proteolytic enzyme secreted in the stomach as pepsinogen and activated by hydrochloric acid. Its primary function is to initiate protein digestion by breaking down large proteins into smaller peptides and free amino acids, making it essential for the digestive process.
Question 3: Diabetes and other potential reasons for low blood sugar.
- Hypoglycemia (Correct answer)
- Glycogen
- Ketoacidosis
- Metabolic Acidosis
Correct answer: Hypoglycemia
Hypoglycemia refers to a condition where blood sugar (glucose) levels drop too low, often associated with diabetes treatment or other medical conditions. This low blood sugar can lead to various symptoms like dizziness, confusion, and weakness, and requires prompt intervention to raise glucose levels.
Question 4: Organ system in charge of gas exchange and both internal and external respiration.
- Respiratory system (Correct answer)
- Endocrine system
- Urinary system
- Circulatory system
Correct answer: Respiratory system
The respiratory system is the organ system specifically responsible for gas exchange, which involves the intake of oxygen and the expulsion of carbon dioxide. This vital process occurs through both external respiration (breathing) and internal respiration (cellular gas exchange), ensuring the body's cells receive necessary oxygen and remove waste products.
Question 5: Blood vessels direct blood toward the heart to replenish oxygen and eliminate waste.
- Artery
- Veins (Correct answer)
- Capillaries
- Arteries
Correct answer: Veins
Veins are blood vessels that are part of the circulatory system, responsible for carrying deoxygenated blood from the body's tissues back towards the heart. This function is crucial for replenishing oxygen in the blood via the lungs and eliminating metabolic waste products from the body.
Question 6: The method of breakdown.
- Lipolysis
- Catabolic (Correct answer)
- Glycolysis
- Anaerobic
Correct answer: Catabolic
Catabolic processes are metabolic pathways that involve the breakdown of complex molecules into simpler ones, releasing energy in the process. This 'method of breakdown' is fundamental for metabolism, providing the body with energy and the necessary building blocks for other cellular functions.
Question 7: Vaporized tiny particles.
- Volatile molecules (Correct answer)
- Hormones
- Dermis
- Odorant-binding proteins
Correct answer: Volatile molecules
Volatile molecules are compounds that readily evaporate at typical room temperatures, releasing tiny particles into the air. These airborne particles are what our olfactory system detects, making them responsible for carrying and transmitting scents.
