Understanding Carbohydrates

The podcast discusses carbohydrates, their types, and roles in energy and structure. It explains monosaccharides, disaccharides, and polysaccharides, focusing on glucose, sucrose, and glycogen. The digestion process, involving enzymes like lactase, is covered, along with the health effects of sugar consumption, highlighting the risks of excessive intake.

What enzyme is required to break down lactose?

• Amylase

• Maltase

• Lactase

• Sucrase

Which of the following is an example of a disaccharide?

• Sucrose

• Galactose

• Fructose

• Glucose

What is the role of oligosaccharides in biology?

• Protein synthesis

• Energy storage

Which polysaccharide is used by plants to store energy?

• Glycogen

• Starch

• Cellulose

• Chitin

What process breaks down polymers into monomers using water?
