Gastrointestinal Questions Questions
Question 1 of 5
The stomach lining contains several types of cells. Which statement about them is correct?
Correct Answer: A
Rationale: The correct answer is A because mucous cells in the stomach lining secrete the glycoprotein mucin, which helps protect the stomach lining from the acidic environment and digestive enzymes. This is crucial for maintaining the integrity of the stomach wall and preventing damage. Chief cells (option B) secrete pepsinogen, not gastrin. Parietal cells (option C) secrete hydrochloric acid and intrinsic factor, not pepsinogen. G cells (option D) secrete gastrin, a hormone that stimulates acid secretion but do not secrete hydrochloric acid directly. Therefore, option A is correct as it accurately describes the function of mucous cells in the stomach lining.
Question 2 of 5
Why is mitochondrial DNA particularly susceptible to damage?
Correct Answer: D
Rationale: The correct answer is D because mitochondria are the main source of reactive oxygen species (ROS), which can damage DNA. Mitochondrial DNA is located near the electron transport chain where ROS are produced. This proximity increases the chances of oxidative damage to the mitochondrial DNA. Choices A, B, and C are incorrect because mitochondrial DNA polymerase does have some proof-reading activity, oxygen content is necessary for mitochondrial function, and mitochondrial DNA damage is not solely due to aging but also due to ROS production.
