Understanding Digestive Enzymes

What is the primary function of amylase in digestion?

• The primary function of amylase in digestion is to break down starch into sugars.

• To emulsify fats for digestion.

• To break down proteins into amino acids.

• To absorb nutrients from food.

Which enzyme is responsible for breaking down proteins?

• Amylase

• Lipase

• Protease

• Cellulase

What role does lipase play in the digestive system?

• Lipase is responsible for breaking down proteins.

• Lipase aids in the digestion of fats by breaking them down into fatty acids and glycerol.

• Lipase helps in the absorption of vitamins.

• Lipase regulates blood sugar levels.

Where is pepsin produced and what does it digest?

• Pepsin is produced in the intestines and it digests vitamins.

• Pepsin is produced in the stomach and it digests proteins.

• Pepsin is produced in the liver and it digests carbohydrates.

• Pepsin is produced in the pancreas and it digests fats.

What is the function of lactase in the digestive process?

• Lactase breaks down proteins in the stomach.

• Lactase is responsible for fat absorption.

• Lactase facilitates the digestion of lactose in the digestive process.

• Lactase produces bile for digestion.

How do digestive enzymes affect nutrient absorption?

• Digestive enzymes have no effect on nutrient absorption whatsoever.

• Digestive enzymes only affect the taste of food, not its absorption.

• Digestive enzymes slow down nutrient absorption by making food harder to digest.

• Digestive enzymes enhance nutrient absorption by breaking down food into simpler molecules that can be easily absorbed.

What is the significance of bile in fat digestion?

• Bile is significant in fat digestion as it emulsifies fats, enhancing their breakdown and absorption.

• Bile helps in the absorption of vitamins only.

• Bile stores carbohydrates for energy.

• Bile is primarily responsible for protein digestion.

Which enzyme is involved in the breakdown of nucleic acids?

• Proteases

• Lipases

• Amylases

• Nucleases

What are the effects of enzyme deficiencies on digestion?

• Enzyme deficiencies have no impact on digestion.

• Enzyme deficiencies can lead to malabsorption, gastrointestinal discomfort, and nutrient deficiencies.

• Enzyme deficiencies only affect taste perception.

• Enzyme deficiencies improve digestion efficiency.

How do enzymes work to speed up chemical reactions in digestion?

• Enzymes increase activation energy to slow down digestion.

• Enzymes convert food into energy without breaking it down.

• Enzymes are not involved in the digestion process at all.

• Enzymes speed up digestion by lowering activation energy and facilitating the breakdown of food molecules.
