Multiple Choice
In the digestive system, what is the primary function of the enzyme amylase?
A
It breaks down proteins into amino acids.
B
It emulsifies fats to increase their surface area for digestion.
C
It breaks down starches (polysaccharides) into smaller sugars such as maltose.
D
It breaks down triglycerides into fatty acids and monoglycerides.
Verified step by step guidance1
Identify the role of enzymes in the digestive system: enzymes catalyze the breakdown of macromolecules into smaller, absorbable units.
Recall that amylase is an enzyme specifically involved in carbohydrate digestion.
Understand that starches are polysaccharides, which are complex carbohydrates made of many glucose units linked together.
Recognize that amylase catalyzes the hydrolysis of starch into smaller sugar molecules, primarily maltose, which is a disaccharide.
Conclude that the primary function of amylase is to break down starches (polysaccharides) into smaller sugars such as maltose, facilitating carbohydrate digestion.
