Flashcards in Chapter 12- Enzymes Deck (18):
1

What is metabolism?

All chemical reactions in an organism

2

What are reactants?

Chemicals that react with each other

3

What are products?

Chemicals produced as the result of the chemical reaction

4

What are anabolic reactions?

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

5

What are catabolic reactions?

Break down of complex chemicals into simpler chemicals
Eg. Respiration

6

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

The sequence of amino acids varies
The way the protein is folded

7

What is a catalyst?

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

8

What is an enzyme?

Protein catalysts found in living organisms

9

What are Proteins?

Long chains of amino acids

10

What is a substrate?

Chemical in which an enzyme reacts

11

Enzyme->Substrate->Product

Amylase->Starch->Maltose

Catalase->Hydrogen Peroxide->Oxygen and water

12

What is an active site?

Place on enzyme where the substrate attached and reaction takes place

13

What is enzyme specificity?

Enzyme will only catalyse one reaction

14

Factors affecting enzyme reaction?

pH
Temperature
Heat denature

15

What is optimum pH?

pH at which the enzyme works beat

16

What is bio processing?

Use of organisms, cells or enzymes to make specific products

17

What are immobilised enzymes?

Biological catalysts attached to an inert material, chemically or physically

18

What is a bio reactor?

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