Salivary amylase begins the digestion of starch in the mouth, breaking it down into:

Answer: Maltose and smaller polysaccharides.

  • A Glucose mainly in most observed cases
  • B Maltose and smaller polysaccharides
  • C Amino acids and peptides under typical physiological conditions
  • D Fatty acids and glycerol according to standard texts

Correct answer: B. Maltose and smaller polysaccharides

Explanation: Salivary amylase hydrolyzes starch into smaller polysaccharides and maltose, though this digestion is incomplete since the enzyme is inactivated by stomach acid.
