Exploring Hydrolysis of Macromolecules

The video tutorial explains dehydration synthesis, where glucose molecules form bonds to create disaccharides like maltose and polysaccharides such as starch, chitin, glycogen, and cellulose. It highlights the structural differences between starch and cellulose and introduces hydrolysis, the process of breaking down these polysaccharides into glucose using water. The tutorial provides a detailed mechanism of hydrolysis, emphasizing its importance in biology for energy conversion.

What is formed when two glucose molecules bond through dehydration synthesis?

• Sucrose

• Maltose

• Lactose

• Fructose

Which of the following is a polysaccharide found in the shells of insects and lobsters?

• Cellulose

• Chitin

• Starch

• Glycogen

What is the primary component of cotton in its natural form?

• Starch

• Chitin

• Cellulose

• Glycogen

What is the main difference in bonding between starch and cellulose?

• Starch has flipped glucose molecules, cellulose does not

• Cellulose is made of fructose, starch is made of glucose

• Cellulose has flipped glucose molecules, starch does not

• Starch is made of fructose, cellulose is made of glucose

What process is used to break down polysaccharides into glucose?

• Hydrolysis

• Oxidation

• Condensation

• Dehydration synthesis

What does the prefix 'hydro' in hydrolysis indicate?

• Light

• Air

• Heat

• Water

What is the role of water in hydrolysis?

• To form new bonds

• To provide energy

• To break bonds

• To stabilize molecules

What happens to the oxygen atom during the hydrolysis of maltose?

• It becomes a free radical

• It loses a positive charge

• It gains a positive charge

• It forms a double bond

What is the result of hydrolysis on maltose?

• One glucose and one galactose molecule

• One glucose and one fructose molecule

• Two glucose molecules

• Two fructose molecules

Which of the following is NOT a product of hydrolysis?

• Maltose

• Glucose

• Fructose

• Sucrose
