Amylase is a digestive enzyme that primarily breaks down which type of carbohydrate?
A
Cellulose into glucose monomers
B
Triacylglycerols into fatty acids and glycerol
C
Lactose into glucose and galactose
D
Starch (amylose and amylopectin) into smaller oligosaccharides and maltose
Verified step by step guidance1
Identify the role of amylase as a digestive enzyme, which means it catalyzes the breakdown of specific macromolecules in the diet.
Recall that carbohydrates are polymers made of sugar monomers, and different enzymes target different types of carbohydrates.
Understand that amylase specifically acts on starch, which is composed of amylose and amylopectin, breaking them down into smaller oligosaccharides and maltose.
Recognize that cellulose is a different polysaccharide that amylase does not break down; instead, cellulose requires cellulase, which humans do not produce.
Note that triacylglycerols are lipids, broken down by lipases, and lactose is a disaccharide broken down by lactase, so these are not substrates for amylase.
