Which enzyme is most essential for the digestion of triglycerides found in butterfat?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
Correct Answer: A
Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

Why are LDLs known as the 'bad' type of cholesterol?
- A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct Answer: A
Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

Sugar alcohols have anticariogenic properties and can protect the teeth by decreasing demineralization, enhancing remineralization, or increasing salivary flow, even in the presence of a fermentable carbohydrate. Name 3 sugar alcohols.
- A. Sorbitol
- B. Mannitol
- C. Xylitol
- D. Erythritol
Correct Answer: D
Rationale: Sugar alcohols such as sorbitol, mannitol, and xylitol are commonly used in sugar-free products and have properties that help protect teeth from caries by promoting remineralization and increasing salivary flow. Erythritol is another common sugar alcohol used as a sweetener in various products, but it was not listed in the question.
Which mental health disorder can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity?
- A. Bulimia
- B. Anorexia nervosa
- C. Depression
- D. Schizophrenia
Correct Answer: A
Rationale: The correct answer is A: Bulimia. Bulimia involves repeated episodes of binge eating followed by purging, which can lead to the erosion of lingual enamel, enlarged parotid glands, palatal bruising, and dentinal hypersensitivity. This behavior exposes the teeth to stomach acid during purging, causing damage to the enamel. Choices B, C, and D are incorrect because these conditions are not typically associated with the specific oral health issues mentioned in the question.
