Enzymes

Question 1

where is lipase produced

Answer 1

-pancreas
-small intestine

Question 2

function of lipase

Answer 2

to break down lipids into fatty acids and glycerol

Question 3

where is protease produced

Answer 3

-stomach
-pancreas
-small intestine

Question 4

function of protease

Answer 4

break down proteins into amino acids

Question 5

where is amylase produced

Answer 5

-salivary glands
-pancreas
-small intestine

Question 6

function of amylase

Answer 6

break down starch into simple sugars and maltose

Question 7

why are enzymes described as specific

Answer 7

each enzyme only catalyses a specific reaction. The active site only fits with certain substrates (lock and key method)

Question 8

what does catalyse mean

Answer 8

speed up a reaction

Question 9

what are enzymes

Answer 9

protein molecules that catalyse specific reactions in organisms

Question 10

why do different enzymes have different optimum pHs

Answer 10

different parts of digestive system have different pHs - e.g. stomach is strongly acidic, small intestine is close to neutral

Question 11

2 factors that affect the rate of activity of an enzyme that can denature it

Answer 11

-temperature
-pH
