Enzymes + Energy Carriers

Question 1

Metabolism

Answer 1

The sum of all chemical reactions in the body

Question 2

Enzymes are…

Answer 2

Globular proteins + usually catalysts

Question 3

How do Enzymes work

Answer 3

They work because they have the right active site to fit the substrate

Question 4

Are enzyme reactions reversible

Answer 4

Yes

Question 5

Anabolic enzyme eg

Answer 5

Dna polymerase

Question 6

Catabolic enzyme eg

Answer 6

Amylase

Question 7

Induced fit theory

Answer 7

When the active site changes slightly to perfectly fit the substrate

Question 8

Enzyme specificity

Answer 8

Each enzyme will only react with 1 substrate

Question 9

Induced fit theory steps

Answer 9

Substrate + enzyme combine, active site is induced.
Enzyme-substrate complex, bonds altered so substrate = product
Products leave + active site reverts

Question 10

Denaturation causes

Answer 10

High temp
Wrong ph

Question 11

Denaturation

Answer 11

When the active site is permanently altered and can’t react with substrate

Question 12

Amylase

Answer 12

Catabolic
Found in salivary glands
Starch - maltose

Question 13

Pepsin

Answer 13

catabolic
found in stomach
Protein - peptides

Question 14

DNA ligase

Answer 14

Ananbolic
joims to pieces of DNA

Question 15

DNA polymerase

Answer 15

Anabolic
Fixes DNA

Question 16

bioprocessing

Answer 16

The use of enzymes controlled reactions to make a product

Question 17

Enzyme Immobilising Methods

Answer 17

Attach to eacbother
Attach to fixed object
Trap in a gel

Question 18

Immobilised enzyme benefits

Answer 18

Produce fructose from glucose
Convert penecilin to different forms - antibiotic resistance
Produce sweet sugars from lactose
