27
End products of aerobic respiration
CO2 + H2O
28
End products of anaerobic respiration
Lactic acid
29
Energy produced during aerobic respiration
Lots of energy
30
Energy produced during anaerobic respiration
Little energy
31
Aerobes
Loving things that get energy from aerobic respiration
32
What happens to the energy stored in the bonds in glucose
It is released | Used to make ATP
33
What happens when ATP breaks down
Supplies energy for all reactions in a cell
34
Example of reactions in a cell
Movement of muscles
35
What percent of energy in glucose is used to make ATP
40%
36
What is lost as heat
Any energy not used to make ATP
37
Glycolysis requires
No oxygen
38
Glycolysis releases
Small amounts of energy
39
Stage 1:
It converts 6 carbon glucose into two 3 carbon molecules | A small amount of ATP is formed
40
Where does stage 2 take place
Mitochondria
41
Stage 2 requires
Oxygen
42
What are found in the mitochondria
Enzymes
43
Stage 2:
3 carbon molecules are broken down to Carbon Dioxide and Water
44
Products formed after stage 1
Small amount of ATP (energy) | Two 3 carbon molecules
45
Products formed at the end of stage 2
Carbon dioxide Water A lot of energy is
46
Less energy release during
Anaerobic respiration
47
Ethanol is
High energy
48
Baking powder is used instead of yeast in
Very hot ovens
49
Biotechnology refers to
Living things to carry out useful reactions
50
Industrial fermentation
Microorganisms is placed in a containers with a suitable substrate they can react on
51
Bioreactor
Vessel in which biological reactions can rake place
52
What is used when microtomes with the substrate foam
Foam beaker
53
Quality of the product produced during a fermentation bioreactor depends on
Design of bioreactor | Correct temperature and pH
54
How are new m.o being produced
Genetic engineering
55
Bacteria can be used to make..
Antibiotics | Yogurts
56
Yeast can be used to make
Beer | Wine
57
Fungi can produce
Antibiotics
58
How do u insure microorganisms are not lost at the end of every reaction
They are immobilized or fixed
59
Example of how microorganisms are immobilized by bonding
Bonding them in a gel or membrane
60
Uses of immobilized cells/ enzymes
In production of alcohol, yeast cells are immobilized with sodium alginate
61
Advantages of immobilized cells
Cells can easily be recovered | Cells can be reused
