Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Maltose is digested into glucose by maltase
A
True
B
False
Explanation: 

Detailed explanation-1: -Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. Commercial maltose is produced from starch that has been treated with barley malt.

Detailed explanation-2: -During digestion, starch is partially transformed into maltose by the pancreatic or salivary enzymes called amylases; maltase secreted by the intestine then converts maltose into glucose.

Detailed explanation-3: -Both maltose and maltotriose are digested by maltase, releasing glucose for absorption. As amylopectin enters the intestinal lumen, pancreatic amylase will also act on its alpha 1-4 linkages, producing maltose and maltotriose, which are converted, to glucose.

Detailed explanation-4: -Maltase is an enzyme secreted by the small intestine that catalyzes the hydrolysis of disaccharides maltose into a simple sugar called glucose.

Detailed explanation-5: -Maltose can be broken down to glucose by the maltase enzyme, which catalyses the hydrolysis of the glycosidic bond.
