Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Contains amylase (degrades starch) and lingual lipase (degrades fat), water, salts, lysozyme (bactericide) and mucin (lubricant).
A
Saliva
B
substance P
C
gastric acids
D
None of the above
Explanation: 

Detailed explanation-1: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase. Starch comprises a significant portion of the typical human diet for most nationalities.

Detailed explanation-2: -Saliva contains the enzyme, salivary amylase. This enzyme breaks the bonds between the monomeric sugar units of disaccharides, oligosaccharides, and starches. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose.

Detailed explanation-3: -The correct answer is Saliva. Saliva contains an enzyme called Lingual Lipase, which helps in breaking down fats. Our saliva plays a significant role in our digestive system. It also contains enzymes like Amylase and Isozyme.

Detailed explanation-4: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.
