Which statement correctly describes amylase and lipase?

• A. They are hydrolases located primarily in the pancreas
• B. They are structural proteins
• C. They are kidney enzymes
• D. They are inflammatory cytokines

Answer: (A)

Amylase and lipase are digestive enzymes that catalyze hydrolysis. Amylase breaks down starches into sugars, while lipase cleaves fats into fatty acids and glycerol. Both are hydrolases, not structural proteins or signaling molecules, and they are produced mainly by the pancreas (lipase mainly from the pancreas; amylase has a significant pancreatic contribution but also comes from salivary glands). This makes a statement about their enzymatic nature and pancreatic origin the best description. They are not kidney enzymes or inflammatory cytokines, which are distinct types of proteins with different roles.
