enzymes in industry

Question 1

why is protease used in industry?

Answer 1

-used to pre-digest proteins during the manufacture of baby foods

Question 2

what is protease use for in industry?

Answer 2

• baby food ( makes it easier to swallow

Question 3

why is isomerase used industry?

Answer 3

• convert glucose syrup into fructose syrup - fructose is sweeter than glucose, so it can be used in smaller amounts

Question 4

what is isomerase used for ?

Answer 4

• slimming food (less is needed )

Question 5

why is carbohydrase used in industry ?

Answer 5

-convert starch syrup, which is relatively cheap, into sugar syrup, which is more valuable

Question 6

why is lipase used industry ?

Answer 6

• to break down - digest - the substances in stains into smaller, water soluble substances

Question 7

what is lipase used for industry ?

Answer 7

• biological detergent (more eco-friendly )

Question 8

what are the advantages of using enzymes in industry ?

Answer 8

• can be cheap once made
• can be reused
• reactions can happen at low temperature therefore less cost on energy
• helps the environment

Question 9

what are disadvantages of using enzymes in industry ?

Answer 9

• easy to denature especially high temperatures
• cost a lot to produce the enzyme
• quite slow to make the enzyme

Question 10

for the enzyme protein what is the substrate and product ?

Answer 10

• substrate = protase

- product = amino acid

Question 11

for the enzyme isomerase what is the substrate and product ?

Answer 11

• substrate = glucose syrup

- product = fructose syrup

Question 12

for the enzyme carbohydrase what is the substrate and product ?

Answer 12

• product = starch

- substrate = sugar syrup

Question 13

what is the advantage of using protease ?

Answer 13

• can help digest food more easily

- increase mass and muscle more quickly

Question 14

what is the advantage of isomerase ?

Answer 14

• much sweeter

- less calories as less is used

Question 15

what is the advantage of carbohyrdase ?

Answer 15

• cheap to make

- can liquidise chocolate for soft centre otherwise it would be solid

Question 16

what does industry do to make soft rented chocolate ?

Answer 16

-filling carbohydrase hardens -> allows chocolate on outside to not melt with filling

Question 17

what do you have to do with baby food before it can be eaten in chunks ?

Answer 17

• food is liquidiesd –.>enzymes are added to it so babies can eat it –> otherwise the babies could not process it in there digestive system

Question 18

equation for lactose ?

Answer 18

• lactose –> glucose + fructose

(lactose breaks down )

Question 19

what does being lactose intolerant mean ?

Answer 19

• an inability to digest lactose which is a sugar found in milk
• or produce lactase to digest the lactose
  not all milk as lactose milk in goats milk has no lactose in it

Question 20

what are the side effects of having lactose when being lactose intolerant ?

Answer 20

• stomach cramps

- dihoreahaa

Question 21

how is non lactose milk made ?

Answer 21

-lactose and sodium alginate mixed –> mixture got into calcium chloride –> little sodium chloride balls —> enzymes get stuck on the outside of the balls —> pour milk over immobilised enzymes = lactose free milk

Question 22

what are the advantages of using immobilised enzymes ?

Answer 22

• can reach a new niece market sell products e.g lactose free milk
• you can reuse enzymes so its not that expensive to make again
• dont haver to spend money to purify the product

Question 23

what are the disadvantages of using immobilised enzymes?

Answer 23

• expensive to first make it

- time consuming to make the product
