Answer :
Final answer:
Pancreatic juice contains important components such as enzymes for digestion and buffers (sodium bicarbonate). It does not contain HCl, CCK, or gastrin. The main role of pancreatic juice is to facilitate the digestion of carbohydrates, fats, and proteins in the small intestine.
Explanation:
Components of Pancreatic Juice
Pancreatic juice is a vital fluid produced by the pancreas that contains several important components for digestion. Let's analyze the options provided:
- Enzymes for digestion: Yes, pancreatic juice contains enzymes such as pancreatic amylase, lipase, and proteases (like trypsin and chymotrypsin) that are crucial for digesting carbohydrates, fats, and proteins.
- HCI: No, hydrochloric acid (HCl) is not found in pancreatic juice. Instead, the pancreas produces sodium bicarbonate to neutralize the acidity of chyme from the stomach.
- Buffers: Yes, sodium bicarbonate acts as a buffer, raising the pH of the chyme and enabling the proper functioning of digestive enzymes in the small intestine.
- CCK (Cholecystokinin): No, CCK is a hormone that stimulates the pancreas to release digestive enzymes but is not a component of pancreatic juice itself.
- Gastrin: No, gastrin is another hormone that stimulates stomach acid production and is not found in pancreatic juice.
In summary, the components found in pancreatic juice are enzymes for digestion and buffers.
