The Role of Digestive Enzymes in Breaking Down Food Molecules

The video explains the digestion process, focusing on how enzymes like amylase, protease, and lipase break down carbohydrates, proteins, and lipids into smaller molecules. It highlights the importance of enzyme shape in their functionality and how factors like temperature and pH can alter enzyme effectiveness.

What is the primary role of enzymes in the digestive process?

• To increase the size of food particles

• To break down large molecules into smaller, soluble ones

• To slow down chemical reactions

• To absorb nutrients directly into the bloodstream

Which enzyme is responsible for breaking down starch into glucose?

• Lactase

• Amylase

• Lipase

• Protease

Where are protease enzymes produced in the body?

• Liver and gallbladder

• Stomach, small intestine, and pancreas

• Large intestine

• Salivary glands

What are the products of lipid digestion by lipases?

• Glucose and fructose

• Amino acids and peptides

• Starch and cellulose

• Glycerol and fatty acids

How can the effectiveness of an enzyme be altered?

• By reducing the enzyme's size

• By altering the temperature or pH

• By changing the enzyme's color

• By increasing the amount of substrate
