QUESTION
Starch is hydrolysed by?
OPTIONS
(A) Hexokinase
(B) Amylase
(C) Phosphorylase
(D) None of these
ANSWER
(B) Amylase
EXPLANATION
Amylase is the correct option because amylase hydrolyzes starch into smaller carbohydrates such as maltose, maltotriose and dextrins. Hexokinase phosphorylates glucose, phosphorylase removes glucose residues from glycogen rather than hydrolyzing dietary starch, and therefore none of those alternatives represents the principal starch-hydrolyzing enzyme.
