Introduction:
The pancreas is a vital organ that secretes pancreatic juice into the small intestine. This juice contains various enzymes that help in the digestion of food. However, not all enzymes are present in pancreatic juice.

Enzymes present in Pancreatic Juice:
1. Trypsin: It is a protease enzyme that helps in the digestion of proteins. It breaks down proteins into smaller peptides.
2. Amylase: It is an enzyme that helps in the digestion of carbohydrates. It breaks down complex carbohydrates into simple sugars.
3. Lipase: It is an enzyme that helps in the digestion of fats. It breaks down fats into fatty acids and glycerol.

Enzymes absent in Pancreatic Juice:
1. Ptyalin: It is an enzyme that helps in the digestion of carbohydrates. However, it is secreted by salivary glands and not by the pancreas.
2. Both B and D: Amylase and Ptyalin are both enzymes that help in the digestion of carbohydrates. However, Ptyalin is not present in pancreatic juice.

Conclusion:
In conclusion, pancreatic juice contains enzymes that help in the digestion of proteins, carbohydrates, and fats. However, Ptyalin, an enzyme that helps in the digestion of carbohydrates, is not present in pancreatic juice.

Explanation: trypsine (digests protein), lipase (digests fats), amalyse (digests carbohydrates) are secreted by pancrease into deodenum of small intestine. So the correct option is (d) (ptyaline), as it is secreted by salivary glands.
