Final answer:
Amylase and lipase are enzymes secreted by the pancreas that help digest carbohydrates and lipids, respectively. Bicarbonate is also secreted by the pancreas to neutralize the acidity of chyme. Bile salts are produced by the liver, not the pancreas, and pepsin is active in the stomach.
Step-by-step explanation:
The substances secreted in pancreatic juice include digestive enzymes and bicarbonate. Included among these enzymes are substances like amylase and lipase, which are responsible for the breakdown of carbohydrates and lipids, respectively.
Bicarbonate is also a crucial component of pancreatic juice, serving to neutralize the acidity of chyme as it enters the small intestine from the stomach. This allows for optimal functioning of digestive enzymes within the intestine. Therefore, the correct options that may be secreted in pancreatic juice from the list given are amylase, lipase, and bicarbonate.
It is important to note, bile salts are not secreted by the pancreas but by the liver, and pepsin is an enzyme active in the stomach, not the pancreas.
The substances that may be secreted in pancreatic juice include amylase, lipase, and bicarbonate. These all play pivotal roles in the digestion process within the small intestine, contributing to the breakdown of various nutrients and neutralizing stomach acids.
