Multiple Choice Questions on Gastrointestinal Disorders Questions
Question 1 of 5
A lipoprotein has the following components: 5% triglyceride, 20% cholesterol, 30% phospholipid, and 45% protein. This molecule would be best described as a
Correct Answer: D
Rationale: The correct answer is D: high-density lipoprotein (HDL). HDL is known to have a higher proportion of protein compared to other lipoproteins. In this case, with 45% protein content, it aligns with the typical composition of HDL. HDL is responsible for transporting cholesterol from peripheral tissues back to the liver for excretion, making it crucial for maintaining cardiovascular health. A: Micelle is incorrect as it is a single-layered structure formed by amphipathic molecules in a specific environment like bile salts in the intestines. B: Chylomicron is incorrect as it is primarily composed of triglycerides and is responsible for transporting dietary lipids. C: Low-density lipoprotein (LDL) is incorrect as it typically has higher cholesterol content compared to HDL and is known as "bad cholesterol" due to its role in depositing cholesterol in arteries.
Question 2 of 5
Consider the following statements regarding the local support and defense system. Which one is true?
Correct Answer: C
Rationale: The correct answer is C because macrophages can indeed infiltrate enlarged adipocytes in obesity. This is a true statement as obesity is associated with chronic low-grade inflammation in adipose tissue, leading to macrophage infiltration. Option A is incorrect as inflammation can also occur in response to tissue damage. Option B is incorrect as inflammation is a normal and necessary response to injury or infection for tissue repair. Option D is incorrect as statement C is true.
Question 3 of 5
During muscle contraction, local metabolites act to vasodilate arterioles supplying the working muscle(s). Which of the following would NOT contribute to a local vasodilation?
Correct Answer: C
Rationale: The correct answer is C because an increase in oxygen does not contribute to local vasodilation during muscle contraction. Oxygen is typically consumed by working muscles and does not act as a vasodilator. On the other hand, increases in carbon dioxide and hydrogen ions lead to vasodilation by stimulating the release of vasodilatory substances. Choice D is incorrect because oxygen, in this context, does not contribute to vasodilation like carbon dioxide and hydrogen ions do.
