Understanding Disaccharides and Polysaccharides

What is the process called when two monosaccharides combine to form a disaccharide?

• Condensation

• Fermentation

• Glycosylation

• Hydrolysis

Which of the following is a disaccharide?

• glucose

• fructose

• sucrose

• lactose

What type of bond is formed during the condensation of monosaccharides?

• Ionic bond

• Hydrogen bond

• Glycosidic bond

• Peptide bond

What is the main product of hydrolysis of sucrose?

• Lactose and Fructose

• Maltose and Glucose

• Glucose and Fructose

• Galactose and Sucrose

Which enzyme is responsible for breaking down disaccharides into monosaccharides?

• Disaccharidases

• Amylase

• Protease

• Lipase

What is the general formula for disaccharides?

• C_nH_(2n)O_(n-1)

• C_nH_(2n-2)O_(n+1)

• C_nH_(2n+2)O_n

• C_nH_(2n)O_n

Which of the following is a polysaccharide?

• starch

• glucose

• cellulose

• fructose

What is the primary function of polysaccharides in living organisms?

• Energy storage and structural support.

• Lipid transport

• Protein synthesis

• DNA replication

During hydrolysis, what molecule is typically added to break down a disaccharide?

• Sucrose

• Water

• Fructose

• Glucose

What is the difference between alpha and beta glycosidic bonds?

• Alpha glycosidic bonds have the -OH group below the sugar ring, while beta glycosidic bonds have it above.

• Alpha glycosidic bonds are stronger than beta glycosidic bonds.

• Alpha glycosidic bonds have the -OH group above the sugar ring, while beta glycosidic bonds have it below.

• Alpha glycosidic bonds are found in proteins, while beta glycosidic bonds are found in carbohydrates.
