Chapter 12- Enzymes

Question 1

What is metabolism?

Answer 1

All chemical reactions in an organism

Question 2

What are reactants?

Answer 2

Chemicals that react with each other

Question 3

What are products?

Answer 3

Chemicals produced as the result of the chemical reaction

Question 4

What are anabolic reactions?

Answer 4

Invoke building up of molecules to form more complex molecules
Eg. Photosynthesis

Question 5

What are catabolic reactions?

Answer 5

Break down of complex chemicals into simpler chemicals

Eg. Respiration

Question 6

How does one enzyme differ from another in terms of nature?

Answer 6

The sequence of amino acids varies

The way the protein is folded

Question 7

What is a catalyst?

Answer 7

Chemical that has the ability to speed up/slow down chemical reactions without being used up

Question 8

What is an enzyme?

Answer 8

Protein catalysts found in living organisms

Question 9

What are Proteins?

Answer 9

Long chains of amino acids

Question 10

What is a substrate?

Answer 10

Chemical in which an enzyme reacts

Question 11

Enzyme->Substrate->Product

Answer 11

Amylase->Starch->Maltose

Catalase->Hydrogen Peroxide->Oxygen and water

Question 12

What is an active site?

Answer 12

Place on enzyme where the substrate attached and reaction takes place

Question 13

What is enzyme specificity?

Answer 13

Enzyme will only catalyse one reaction

Question 14

Factors affecting enzyme reaction?

Answer 14

pH
Temperature
Heat denature

Question 15

What is optimum pH?

Answer 15

pH at which the enzyme works beat

Question 16

What is bio processing?

Answer 16

Use of organisms, cells or enzymes to make specific products

Question 17

What are immobilised enzymes?

Answer 17

Biological catalysts attached to an inert material, chemically or physically

Question 18

What is a bio reactor?

Answer 18

Vessel that cells, organisms or enzymes are placed into to manufacture specific products
