Define what is respiration
Differentiate aerobic from anaerobic respiration
Explain the 4 main stages of aerobic respiration
Explain the process of fermentation
Blood, sweat, and tears were put in to this! Use it and abuse it! Here is the ultimate study buddy for you to ace the test. All the material was derived from class notes, extra help, and of course Mr. Williamsen himself! ENJOY!!!
5. There is energy locked up in
each bond
Energy is released
when bonds
break
A glucose molecule Wastes
C6H12O6 CO2 & H2O
6. TWO forms of energy are
released from food:
1. ATP (adenosine triphosphate)
2. heat
7. ATP:
can be moved about inside a cell
is a store of energy inside cells
ADENOSINE
8. What do you conclude from this
experiment:
A drop of glucose A drop of ATP
solution is put on solution is put on
a muscle: a muscle:
nothing happens it contracts
Glucose by itself cannot provide the
energy but ATP can.
9. Respiration builds ATP
ADP + P + energy from → ATP
glucose
Adenosine Phosphate Adenosine
diphosphate triphosphate
energy
from
glucose
10. The body can use the energy released when
ATP is broken down:
energy able
ATP → ADP + P + to do work
29. RESULT:
Lime water A: Lime water B:
remains clear. turns milky.
30. CONCLUSION:
Since lime water A remained clear, this
indicates that all of the carbon dioxide
in the original incoming air had been
removed by the sodium hydroxide.
Since lime water B turned milky, shows
that carbon dioxide was produced by
the green plant during respiration.
39. Why does it occur?
Muscles resort to anaerobic
respiration when oxygen is not
delivered to them fast enough.
I need 10 units of oxygen
BUT am getting 5 units!!
40. Lactic acid
is a mild poison and
causes the muscles to ache
causes:
fatigue
& sometimes cramps
41. Lactic acid is removed from
muscle by the bloodstream and is
glucose lactic
acid
Blood
CO2 lactic
H2O acid
broken down
Liver
in the liver
42. What is needed for lactic acid to
be broken down in the liver?
43. Oxygen debt:
is the oxygen needed to get rid of the
lactic acid
lactic acid + O
2
CO2 + H2O
44. Explain why:
After activity that has lead to anaerobic
respiration, the person involved pants
and breathes heavily.
To pay the oxygen debt.
50. How would you
modify the
apparatus to
keep a constant
temperature?
Place flask in a
water bath.
51. RESULT:
Living yeast: The lime water turned milky.
Boiled yeast: No colour change in the lime
water.
CONCLUSION:
The living yeast respired anaerobically
and released carbon dioxide. This can be
concluded since the carbon dioxide turns
lime water (calcium hydroxide) cloudy.
52. If apparatus is left for many days, no
bubbles are given off. Give two
reasons.
1. No glucose
left.
2. Yeast died.
53. Question: SEP, 2012
A biology student compared the rates of
fermentation of glucose and sucrose
solutions using yeast. The student set up
the apparatus above using water instead of
limewater. The time to produce 10 gas
bubbles was recorded. The experimental
apparatus was first set up with glucose and
then repeated with sucrose.
i) What other apparatus would the
students need to obtain their results? (1)
A control.
54. Question: SEP, 2012
i) Identify the solution that would give a
faster rate of reaction and give ONE
reason for your answer. (4)
Glucose.
Monosaccharide which is used right
away. Sucrose is a disaccharide and
must be first broken down into
monsaccharides before used for
respiration.
55. Question: SEP, 2010
Give a biological explanation for each of
the following statements:
Lactic acid builds up in muscle cells after
heavy exercise. (4)
56. Question: SEP, 2011
Give a biological explanation for each of
the following statements:
The rate and depth of breathing change
during and after exercise. (5)
58. Aerobic respiration Anaerobic respiration
1) More energy is released Less energy is released
2) Needs oxygen Oxygen is not needed
3) Occurs inside
Occurs in the cytoplasm
mitochondria
4) Glucose is completely Glucose is partially broken
broken down down
5) CO2 and H2O are the Wastes in yeast:
waste materials CO2 & ethanol
Waste in animals:
lactic acid
59. List four ways in which respiration differs
from photosynthesis.
60. Respiration Photosynthesis
1. Occurs all the time. 1. Occurs only in light.
2. Occurs in all 2. Occurs in green
organisms. plants.
3. Releases carbon 3. Releases oxygen
dioxide.
4. Uses food. 4. Builds food.
61. THE END It’s great to be
energetic – I can
study all day
long!!!
