True or False: Maltose, sucrose, and lactose are all types of polysaccharides.

True or False: Maltose, sucrose, and lactose are all types of polysaccharides.

• A. True
• B. False
• C. They are disaccharides
• D. They are all sugars

Answer: (B)

Maltose, sucrose, and lactose are classified as disaccharides, which are sugars composed of two monosaccharide molecules linked together. Each of these sugars has a unique composition: maltose is made up of two glucose units, sucrose consists of glucose and fructose, and lactose is formed from glucose and galactose. In contrast, polysaccharides are carbohydrates that consist of long chains of monosaccharides and can include compounds like starch, glycogen, and cellulose. Since maltose, sucrose, and lactose do not meet the definition of polysaccharides due to their smaller structure, the statement is false.
