Multiple Choice
Which enzyme primarily catalyzes the breakdown of dietary carbohydrates (starch) into smaller sugars during digestion?
A
Lipase
B
Trypsin
C
Amylase
D
Pepsin
Verified step by step guidance1
Identify the substrate involved in the problem, which is dietary carbohydrates, specifically starch.
Recall the main enzymes involved in digestion and their specific substrates: Lipase acts on lipids, Trypsin acts on proteins, Pepsin also acts on proteins, and Amylase acts on carbohydrates.
Understand that the breakdown of starch, a polysaccharide, requires an enzyme that hydrolyzes glycosidic bonds in carbohydrates.
Recognize that Amylase catalyzes the hydrolysis of starch into smaller sugars like maltose and dextrins during digestion.
Conclude that among the given options, Amylase is the enzyme primarily responsible for breaking down dietary starch into smaller sugars.
