Answer 1

In human digestive system, the enzymes pepsin and trypsin are secreted respectively by stomach and pancreas.

Explanation:

Both of these enzymes are responsible for digesting proteins, but they are produced in different locations:

• Pepsin is secreted by the gastric glands of the stomach. It requires the acidic environment of the stomach to actively begin breaking down proteins into smaller peptides.
• Trypsin is secreted by the pancreas (as part of pancreatic juice). It is released into the small intestine, where it continues the chemical breakdown of those protein fragments.
