Free ACBN Nutritionist Trivia Questions and Answers

Question 1

BCAAs are a necessary amino acid and are crucial for energy during exercise.

Accepted Answer

Pepsin

Answer

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.

Accepted Answer

Pepsin

Answer

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.

Accepted Answer

Hypoglycemia

Answer

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.

Accepted Answer

Respiratory system

Answer

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.

Accepted Answer

Veins

Answer

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.
