Final answer:
C) maltase.
Maltose is hydrolyzed into two glucose units by the enzyme maltase. Maltase is essential for digesting malt sugar, converting it into monosaccharides that can be absorbed by the body for energy.
Step-by-step explanation:
Maltose is hydrolyzed into monosaccharides by the enzyme maltase. This enzyme is responsible for breaking down the disaccharide maltose into two glucose units, a necessary step in the digestive process. Maltose, commonly known as malt sugar, is a product of starch and glycogen hydrolysis and can be found for instance in sprouting grains and in the manufacture of beer. The human body cannot directly metabolize disaccharides without this enzymatic action as the molecules are too large to pass through the intestinal wall. Accordingly, specific enzymes like maltase are crucial for converting these sugars into absorbable monosaccharides which can then be transported through the bloodstream to various cells for energy.
