Detailed explanation-1: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.

Detailed explanation-2: -The digestion of starch begins with salivary amylase, but this activity is much less important than that of pancreatic amylase in the small intestine. Amylase hydrolyzes starch, with the primary end products being maltose, maltotriose, and a-dextrins, although some glucose is also produced.

Detailed explanation-3: -Amylase breaks down long chain saccharides (sugars, starch in this case) into smaller sugars such as maltose. It does this using a water molecule to break the glycosidic bonds in the starch compound. A catalyst is a substance that increases the rate of reaction without being used up.

Detailed explanation-4: -The digestive enzyme amylase secreted by the pancreas and some salivary glands is responsible for the initial process of digestion of dietary starch. In the Western world, adults consume about 400 g of carbohydrates each day, with starches and sucrose providing the largest sources.

Detailed explanation-5: -There are two kinds of amylase enzymes: Alpha-amylase (ptyalin), which is produced by the salivary glands. This enzyme begins starch digestion in the mouth and continues to work in the stomach. Pancreatic amylase, which is secreted by the pancreas into the small intestine.
