The enzyme that breaks down polysaccharides, which is produced by the salivary glands and the pancreas is?...a.amylaseb.hydrochloric acidc.biled.saliva

The enzyme that breaks down polysaccharides is amylase. Amylase is produced in both the salivary glands and the pancreas. It plays a critical role in the digestion of carbohydrates, specifically in hydrolyzing the bonds in starches and polysaccharides to yield simpler sugars.

When food is ingested, the salivary amylase starts the process of carbohydrate digestion in the mouth by breaking down starches into maltose and dextrin. Further digestion occurs in the small intestine, where pancreatic amylase continues this breakdown into monosaccharides, facilitating absorption in the intestines.

To summarize, the correct answer to your question is a. amylase.
