Answer: The statement "The production of bile is stimulated by cholecystokinin" is true. (Option 1)
Step-by-step explanation:
Statement 1: The small intestine releases the hormone cholecystokinin (CCK) in reaction to the consumption of food, particularly fatty meals. It encourages the liver and gallbladder to produce and discharge bile. In the breakdown and absorption of lipids, bile is an essential component.
Statement 2: Another hormone produced by the small intestine, secretin's main function is to trigger the production of pancreatic juices, which are composed of water, bicarbonate ions, and digestive enzymes. The bile does not directly respond to secretin when it is released into the duodenum.
Statement 3: There are no concentrated enzymes in bile. Instead, it includes bile salts that help with the digestion and emulsification of lipids. The surface area available for the activity of lipases, which are enzymes involved in lipid digestion, is increased when giant fat globules are broken down into smaller droplets by bile salts.
