The majority of lipase is produced by the

Correct Answer: C

Rationale: The correct answer is C: pancreas. The pancreas is the main source of lipase production in the body. Lipase is an enzyme responsible for breaking down fats into fatty acids and glycerol. The pancreas secretes pancreatic lipase into the small intestine where it aids in the digestion of fats. Salivary glands produce amylase for carbohydrate digestion, the stomach produces gastric lipase for limited fat digestion, and the small intestine produces additional digestive enzymes but not the majority of lipase.

Correct Answer: C

Rationale: The correct answer is C because the formation of tripartite synapses with astrocytes and neurons does not provide direct protection to the brain. Tripartite synapses involve communication between neurons and astrocytes, primarily for synaptic regulation and plasticity. The blood-brain barrier (A) physically protects the brain by restricting the passage of harmful substances. Microglia (B) function as the brain's immune cells, defending against pathogens and removing cellular debris. Therefore, choices A and B contribute to the brain's protection, making them incorrect answers.

Correct Answer: A

Rationale: Rationale: A is false because exercise has been shown to be as effective as, or even more effective than, metformin in slowing the progression of type 2 diabetes. Exercise helps improve insulin sensitivity and manage blood glucose levels, which are crucial for diabetes management. Choices B and C are true statements supported by scientific evidence. Choice D is incorrect as A is false, making the statement "none of the above are false" inaccurate.
