Gastrointestinal Test Questions Questions
Question 1 of 5
The lipids that can be absorbed across the epithelial wall of the small intestine are hydrophobic and would have a difficult time in the watery lumen to come in contact with the epithelial membrane. These lipids are able to move easily in the watery lumen because of interaction with
Correct Answer: C
Rationale: The correct answer is C: micelles. Micelles are formed when bile salts interact with hydrophobic lipids, such as triglycerides, in the watery lumen of the small intestine. This interaction allows the lipids to be emulsified and solubilized in the watery environment, making it easier for them to come in contact with the epithelial membrane for absorption. Lipase (B) is an enzyme that breaks down lipids but does not aid in the movement of lipids in the watery lumen. Bile salts (A) help emulsify lipids but do not facilitate the movement of lipids in the watery lumen. Chylomicrons (D) are large lipoprotein particles formed after absorption of lipids into enterocytes, not involved in the initial movement of lipids in the watery lumen.
Question 2 of 5
Neural networks can be categorized by the main neurotransmitter involved - for example, the dopamine network, the norepinephrine network, etc. Which of the following statements below describing these networks is false?
Correct Answer: C
Rationale: The correct answer is C because inhibition of the dopamine network is not associated with drug addictions; rather, it is often linked to reward, pleasure, and reinforcement in addiction. Parkinson's disease is associated with a loss of the dopamine network (A), cholinesterase inhibitors increase acetylcholine levels to treat Alzheimer's symptoms (B), and some stimulants work through the activation of the norepinephrine network (D).
Question 3 of 5
Which of the following statements is false about the effects of exercise?
Correct Answer: D
Rationale: The correct answer is D because all three statements are true. A is supported by research showing lower risk of death from breast cancer in higher aerobic fitness groups. B is backed by studies indicating increased brain volume with aerobic exercise in the elderly. C is also true, as higher aerobic fitness levels are associated with reduced risk of colon cancer. Therefore, option D is the correct choice as none of the statements are false.
