Which bonds are hydrolyzed during the breakdown of starch during digestion?
a.) 1 and 4
b.) 1 and 3
c.) 1 and 2
d.) 3 and 4
e.) 2 and 3

A) 1 and 4

Alpha amylase is an enzyme which helps in the digestion of starch. Its digestion begins in the mouth.

Starch is a form of complex carbohydrate i.e consisting of multiple sugar units (polysachharides). It a mixture of amylose (  linked glucose polymers ) and amylopectin ( linked glucose polymers branched by linkage)

Alpha-amylase performs the digestion of starch by hydrolyzing glucosidic bond.

a and c are the answeres
