Digestive Enzymes

Question 1

Which enzyme breaks down lipids?

Answer 1

Lipase

Question 2

Which enzyme breaks down carbohydrates?

Answer 2

Carbohydrase

Question 3

Which enzyme breaks down protiens?

Answer 3

Protease

Question 4

What do lipids get broken down into?

Answer 4

Fatty acids + glycerol

Question 5

What do carbohydrates get broken down into?

Answer 5

Simple sugars (e.g. starch → glucose)

Question 6

What do proteins get broken down into?

Answer 6

Amino Acids

Question 7

Where is lipase found?

Answer 7

Small intestine, Pancreas

Question 8

Where is carbohydrase found?

Answer 8

Pancreas, small intestine, (amylase is found in salivary glands in the mouth)

Question 9

Where is protease found?

Answer 9

Stomach, small intestine, pancreas

Question 10

Role of bile

Answer 10

It’s alkaline so it neutralises the HCl in the stomach, making the optimum conditions for the enzymes in the small intestine

It also emulsifies lipids by converting larger droplets to smaller ones, increasing the surface area for lipase enzymes to work on → increasing rate of digestion
