Gastrointestinal Questions Questions
Question 1 of 5
Lipids are emulsified by ______ and digested by ______.
Correct Answer: C
Rationale: The correct answer is C: bile salts; lipase. Bile salts emulsify lipids by breaking them down into smaller droplets to increase the surface area for digestion by lipase. Lipase is the enzyme responsible for digesting lipids into fatty acids and glycerol. Option A is incorrect because lipase digests lipids, not bile salts. Option B is incorrect because amylase digests carbohydrates, not lipids. Option D is incorrect because pepsin is an enzyme that digests proteins, not lipids.
Question 2 of 5
Neurons interact with each other in complex ways, forming networks. Which statement is true regarding neural networks in the brain?
Correct Answer: B
Rationale: The correct answer is B because during the teen years, the brain undergoes significant changes in neural connections. New connections are formed through processes like synaptic pruning, which strengthens important connections and eliminates unnecessary ones. This dynamic phase is crucial for learning and adapting to new experiences. Choices A, C, and D are incorrect because neural networks in the brain are not static and unchanging. The brain continues to reorganize and adapt throughout life, with myelination increasing to improve signal transmission efficiency, not decreasing as in choice D. Choice C is also incorrect as brain size does not significantly increase during the teen years, but rather the focus is on optimizing existing neural connections.
Question 3 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.
