Detailed explanation-1: -Saliva contains the enzyme amylase, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. Hence, the statement is correct.
Detailed explanation-2: -The statement is false. Saliva contains salivary amylase(ptyalin) that converts starch into maltose.
Detailed explanation-3: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.
Detailed explanation-4: -Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
Detailed explanation-5: -Saliva contains the enzyme, salivary amylase. This enzyme begins carbohydrate digestion by breaking some of the bonds between individual units of disaccharides, oligosaccharides, and starches. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose.
