In the small intestine, which of the following enzymes breaks down oligosaccharides?
A
Maltase
B
Lipase
C
Amylase
D
Pepsin
Verified step by step guidance1
Understand the function of each enzyme listed in the options: Maltase, Lipase, Amylase, and Pepsin. Maltase breaks down maltose (a disaccharide) into glucose, Lipase breaks down lipids into fatty acids and glycerol, Amylase breaks down starch into smaller polysaccharides or maltose, and Pepsin breaks down proteins into smaller peptides.
Focus on the term 'oligosaccharides' in the question. Oligosaccharides are carbohydrates composed of a small number of monosaccharide units. They need to be broken down into simpler sugars for absorption.
Identify which enzyme specifically targets oligosaccharides. Maltase is the enzyme that breaks down maltose (a disaccharide derived from oligosaccharides) into glucose, making it relevant to the breakdown of oligosaccharides.
Eliminate the other options based on their functions: Lipase targets lipids, Amylase targets starch (not oligosaccharides directly), and Pepsin targets proteins. These enzymes are not involved in breaking down oligosaccharides.
Conclude that Maltase is the correct enzyme responsible for breaking down oligosaccharides in the small intestine.
