Digestive food enzymes - Organisation

Question 1

…. is a polymer of glucose, produced by plant

Answer 1

Starch

Question 2

What ‘enzyme’ breaks down starch and what are the products?

Answer 2

Amylase breaks down starch into ‘maltose’ molecules
then further broken down by ‘maltase’ into ‘glucose’

Question 3

What enzyme breaks down lipids and what are the products?

Answer 3

Lipases break down lipids into ‘glycerol and fatty acids’

Question 4

What enzyme breaks down proteins and what are the products?

Answer 4

Proteases break down proteins into ‘amino acids’

Question 5

What is a carbohydrase and give one example?

Answer 5

Carbohydrases break down carbohydrates to simple sugars.
Amylase is a carbohydrase which breaks down starch.

Question 6

What is known as ‘digestive enzymes’?

Answer 6

Digestive enzymes convert food into small soluble molecules that can be
absorbed into the bloodstream.

Question 7

What is ‘Bile’ and where is it located in the body?

Answer 7

Bile is a yellow-greenish liquid released from the gall bladder that helps with lipid digestion, however it is not an enzyme.

Question 8

How does bile help with the digestion of lipids? (2marks)

Answer 8

It ‘emulsifies’ the lipids
which ‘increases the SA’ for the lipids to break down.

Question 9

Where is ‘Amylase’ produced?

Answer 9

Salivary glands
Pancreas
Small intestine

Question 10

Where is ‘Protease’ produced?

Answer 10

Stomach(called ‘pepsin’ here)
Pancreas
Small intestine

Question 11

Where is ‘Lipase’ produced?

Answer 11

Pancreas
Small intestine
