Answer 14

They remain unchanged in the chemical reaction

Question 15

What do we call the substance an enzyme acts on

Answer 15

Enzymes are specific to their substrate

Question 16

What is a substrate

Answer 16

Enzymes are specific. They can only bind to one substance which we call a substrate

Question 17

What method is enzymes and their substrates use

Answer 17

Lock and key

Question 18

What is a active site

Answer 18

Enzymes have an active site. It has a very particular shape, and is where the enzyme specific substrate will bind

Question 19

What’s an enzyme substrate complex

Answer 19

When the substrate binds with the enzyme an enzyme substrate complex forms facilitating the reaction

Question 20

What are the products of enzyme

Answer 20

The action of the enzyme results in product(s) being produced

Question 21

What the two kinds of reactions and name that are controlled by enzymes

Answer 21

Degradation =break down reaction
Synthesis =build up reaction

Question 22

How do we indicate reduced sugars

Answer 22

Benedict’s solution is used as an indicator for reduced sugars ( blue to orange )

Question 23

How do we know starch is presence

Answer 23

Iodine is used as an indicator of start presence by turning black

Question 24

Answer 24

Maltose

Question 25

Definition of a biological catalyst

Answer 25

A chemical that speeds up chemical reaction

Question 26

Definition of a biological catalyst

Answer 26

A chemical that speeds up chemical reaction

Question 27

Definition of a biological catalyst

Answer 27

A chemical that speeds up chemical reaction

Question 28

A c______ is a c______

Answer 28

Control
Comparison

Question 29

What’s dose a control is a comparison mean

Answer 29

Experiment to prove that it is the independent variable which is causing the result

Question 30

What is a independent variable

Answer 30

The variable that is changed in an experiment

Question 31

Calculate how many times greater the concentration of product was after 40 minutes than at the start of product at 0mins was 12 and product at 40mins is 96

Answer 31

8

Because if you divide 12 by 96 you get 8 so 12 times 8 is 96

Question 32

Calculate how many times lower the substance was after 40 minutes than at the start of product at 0mins was 36 and product at 40mins is 0.13

Answer 32

4.68

As you times the 40min number 0.13 by the 0min number 36 you get 4.68
