Respiration 1 Flashcards
Respiration
Chemical breakdown of glucose to release energy
Internal respiration is controlled by
Enzymes which allow energy to be released in small amounts
What type of food is involved in respiration
Glucose
Respiration is carried out in the
Mitochondria
Energy trapped in molecules in called
ATP
What type of reaction is Respiration
Catabolic
ATP
Adenosine triphosphate
ADP
Adenosine diphosphate
Types of respiration
Aerobic
Anaerobic
Aerobic respiration
Release of energy from good in the presence of oxygen
Anaerobic
The release of energy from food without requiring the presence of oxygen
Eh of anaerobic respiration
Yeast
Word equation
Glucose + oxygen -> carbon dioxide + water + energy
Name the two stages of aerobic respiration
Glycolysis
Krebs cycle
Where does glycolysis occur
The cytosol of the cytoplasm
Cytosol
Liquid part of the cytoplasm
Krebs cycle occurs in
The mitochondria
More folds more.. is produced
Mitochondria
What are in the folds of mitochondria
Electron transport system
What is anaerobic respiration also known as
Fermentation
Name the two fermentation in anaerobic respiration
Lactic acid fermentation
Alcohol fermentation
How is lactic acid formed
In animal muscles when there is not enough oxygen
Equation for lactic acid fermentation
Glucose -> 2 lactic acid + ATP
Alcohol fermentation
Bacteria and yeast
Ethanol and carbon dioxide is produced
Equation for alcohol fermentation
Glucose -> 2 ethanol + 2 carbon dioxide + ATP
Location of anaerobic respiration
Cytoplasm
End products of aerobic respiration
CO2 + H2O
End products of anaerobic respiration
Lactic acid
Energy produced during aerobic respiration
Lots of energy
Energy produced during anaerobic respiration
Little energy
Aerobes
Loving things that get energy from aerobic respiration
What happens to the energy stored in the bonds in glucose
It is released
Used to make ATP
What happens when ATP breaks down
Supplies energy for all reactions in a cell
Example of reactions in a cell
Movement of muscles
What percent of energy in glucose is used to make ATP
40%
What is lost as heat
Any energy not used to make ATP
Glycolysis requires
No oxygen
Glycolysis releases
Small amounts of energy
Stage 1:
It converts 6 carbon glucose into two 3 carbon molecules
A small amount of ATP is formed
Where does stage 2 take place
Mitochondria
Stage 2 requires
Oxygen
What are found in the mitochondria
Enzymes
Stage 2:
3 carbon molecules are broken down to Carbon Dioxide and Water
Products formed after stage 1
Small amount of ATP (energy)
Two 3 carbon molecules
Products formed at the end of stage 2
Carbon dioxide
Water
A lot of energy is
Less energy release during
Anaerobic respiration
Ethanol is
High energy
Baking powder is used instead of yeast in
Very hot ovens
Biotechnology refers to
Living things to carry out useful reactions
Industrial fermentation
Microorganisms is placed in a containers with a suitable substrate they can react on
Bioreactor
Vessel in which biological reactions can rake place
What is used when microtomes with the substrate foam
Foam beaker
Quality of the product produced during a fermentation bioreactor depends on
Design of bioreactor
Correct temperature and pH
How are new m.o being produced
Genetic engineering
Bacteria can be used to make..
Antibiotics
Yogurts
Yeast can be used to make
Beer
Wine
Fungi can produce
Antibiotics
How do u insure microorganisms are not lost at the end of every reaction
They are immobilized or fixed
Example of how microorganisms are immobilized by bonding
Bonding them in a gel or membrane
Uses of immobilized cells/ enzymes
In production of alcohol, yeast cells are immobilized with sodium alginate
Advantages of immobilized cells
Cells can easily be recovered
Cells can be reused
