Verified step by step guidance
1
Understand that starch is a polysaccharide composed of glucose units linked by glycosidic bonds.
Recognize that the breakdown of starch into glucose involves two main steps: the initial breakdown into maltose and then the conversion of maltose into glucose.
Identify that amylase is the enzyme responsible for breaking down starch into maltose by cleaving the α-1,4-glycosidic bonds.
Recognize that maltase is the enzyme that hydrolyzes maltose into two glucose molecules by breaking the α-1,4-glycosidic bond in maltose.
Conclude that the pair of enzymes required to fully break down starch into glucose is amylase and maltase.
