The correct Answer is:
To analyze the given statements, we will break down each statement and determine their validity. ### Step 1: Analyze Statement A - **Statement A** claims that pancreatic juice contains trypsin, chymotrypsin, carboxypeptidase, amylase, lipase, and nuclease in their active state. - **Fact Check**: - Trypsin, chymotrypsin, and carboxypeptidase are indeed enzymes involved in protein digestion, but they are secreted in their inactive forms (trypsinogen, chymotrypsinogen, and procarboxypeptidase) to prevent the digestion of the pancreas itself. - They are activated in the duodenum by the enzyme enterokinase (which activates trypsinogen to trypsin) and then trypsin activates the other two. - Amylase, lipase, and nuclease, on the other hand, are secreted in their active forms. - **Conclusion**: Therefore, Statement A is **false** because it incorrectly states that all these enzymes are in their active forms. ### Step 2: Analyze Statement B - **Statement B** states that pancreatic juice is released via the hepatopancreatic duct into the duodenum. - **Fact Check**: - The pancreas has a duct known as the duct of Wirsung, which connects with the common bile duct (from the liver and gallbladder) to form the hepatopancreatic duct. - This duct opens into the duodenum, allowing the pancreatic juice to enter the digestive tract. - **Conclusion**: Therefore, Statement B is **true**. ### Final Conclusion - Since Statement A is false and Statement B is true, the overall conclusion is that Statement A is incorrect while Statement B is correct. ### Answer - **Statement A is false; Statement B is true.**
