Which of the following enzymes is involved in the breakdown of proteins?
- A. amylase
- B. lipase
- C. pepsin
- D. maltase
Correct Answer: C
Rationale: The correct answer is C: pepsin. Pepsin is an enzyme produced in the stomach that helps break down proteins into peptides. It works in a highly acidic environment, denaturing proteins. Amylase (A) breaks down carbohydrates, lipase (B) breaks down fats, and maltase (D) breaks down maltose into glucose. Pepsin is specifically designed to target proteins, making it the correct choice.
You have a situation where the hepatopancreatic ampullar sphincter or sphincter of Oddi will not relax. You would expect
- A. chyme not to be released into the stomach.
- B. the feces to contain a much higher percentage of fat than normal.
- C. the feces to contain a much higher percentage of starch and protein than normal.
- D. chyme not to be released into the large intestine.
Correct Answer: B
Rationale: The correct answer is B: the feces to contain a much higher percentage of fat than normal. The hepatopancreatic ampullar sphincter controls the release of bile and pancreatic enzymes into the duodenum to aid in fat digestion. If it does not relax, fat digestion would be impaired, leading to undigested fat in feces. A: Chyme is the semi-liquid mixture of food and digestive juices in the stomach, not affected by this sphincter. C: Starch and protein digestion mainly occur in the stomach and small intestine, not directly influenced by this sphincter. D: Chyme enters the large intestine after passing through the small intestine, not controlled by this sphincter directly.
Which of the following is not a part of the digestive system?
- A. Liver
- B. Gallbladder
- C. absorption-neet-mcq/ 8/13 1/17/25, 2:54 PM Digestion and Absorption NEET MCQ 2024
- D. Lungs
Correct Answer: D
Rationale: The correct answer is D: Lungs. The lungs are not a part of the digestive system. The digestive system is responsible for breaking down food into nutrients, absorbing those nutrients, and eliminating waste. The lungs are part of the respiratory system, responsible for gas exchange. Liver (A) and gallbladder (B) are both part of the digestive system, aiding in digestion and nutrient absorption. Absorption (C) is a process within the digestive system, not a separate entity. In summary, the lungs do not play a role in the digestion process, making them the correct answer choice.
When teaching a patient about weight reduction diets
- A. the nurse teaches the patient that an appropriate single serving of a food is
- B. a 6-inch bagel.
- C. 1 cup of chopped vegetables.
- D. a piece of cheese the size of three dice.
Correct Answer: D
Rationale: A serving of protein is typically the size of a deck of cards (approximately 3-4 oz), which helps patients understand appropriate portion sizes.
Branches of which autonomic nerve carry the parasympathetic motor neurons to the enteric plexi?
- A. oculomotor
- B. facial
- C. glossopharyngeal
- D. vagus
Correct Answer: D
Rationale: The correct answer is D: vagus. The vagus nerve carries parasympathetic motor neurons to the enteric plexi located in the gastrointestinal tract. It innervates most of the organs in the thorax and abdomen, controlling functions like digestion and heart rate. Choices A, B, and C are incorrect because they do not carry parasympathetic motor neurons to the enteric plexi. Oculomotor (A) innervates muscles responsible for eye movement, facial (B) innervates facial muscles and salivary glands, and glossopharyngeal (C) innervates the tongue and pharynx, but they do not specifically target the enteric plexi in the gastrointestinal tract.
