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.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
