Photosynthesis and
Cellular Respiration
What does “ADP” stand for?
_________________________________
adenosine diphosphate
During photosynthesis, CO2 is used to
make glucose in a process called
carbon dioxide fixation
What is the ultimate source of energy
for all plants and animals on Earth?
the sun
During photosynthesis, what are the 2
inorganic molecules that, along with
sunlight, form glucose?
CO2 and H2O
Photosynthesis or Respiration?
- is aerobic
respiration
What is the name of the pigment
found in a majority of plants?
chlorophyll
Put the following molecules in order
based on their energy storing
capabilities (from highest to lowest).
ADP
ATP
AMP
ATP, ADP, AMP
What type of cellular respiration
occurs when oxygen is required?
aerobic respiration
What is the chemical formula for
glucose?
C6H12O6
Photosynthesis or Respiration?
- requires CO2
photosynthesis
Specifically, where is the energy stored
in an ATP molecule?
in the P-bonds
Write the chemical equation for
cellular respiration.
_________________________________
C6H12O6 + 6O2  6CO2 + 6H2O + 38 ATP
True or False… Photosynthesis
requires oxygen.
False
What is the pigment that gives leaves,
vegetables and some flowers their
orange/yellow colors?
carotenoids
What does “ATP” stand for?
_________________________________
adenosine triphosphate
What is the name of the process that
converts light energy into chemical
energy?
photosynthesis
During photosynthesis, how are the
electrons replaced that leave the
chlorophyll?
water is split
When glucose is broken down in the
absence of oxygen it is an anaerobic
process called
fermentation
The series of proteins in the thylakoid
membrane that carries electrons is
called the
electron transport chain
When water is split during
photosynthesis, what 3 products
result?
electrons,
+
H,
and O2
How many turns of the Calvin cycle
are needed to produce 1 glucose
molecule?
6
Write the chemical equation for
photosynthesis.
_________________________________
6CO2 + 6H2O  C6H12O6 + 6O2
Photosynthesis or Respiration?
- breaks down glucose
respiration
Photosynthesis or Respiration?
- produces large amounts of ATP
respiration
Photosynthesis or Respiration?
- electron transport chain produces
small amounts of ATP and NADPH
photosynthesis
What is the name of the disk-shaped
structures in chloroplasts? (they
contain the pigments)
thylakoids
What are the 2 products of alcoholic
fermentation?
CO2 and ethyl alcohol (ethanol)
When the muscles of the body “run
out” of oxygen, what process takes
place that allows your muscles to
continue to contract?
lactic acid fermentation
Photosynthesis or Respiration?
- carbon dioxide fixation
photosynthesis
What molecule is the final electron
acceptor in the electron transport
chain of cellular respiration?
oxygen
In which organelle does cellular
respiration take place?
mitochondria
Why do leaves turn yellow during the
fall?
the chlorophyll is broken down and
stored in the twigs, allowing the
yellow color to show through (it was
there all along)
Photosynthesis or Respiration?
- occurs in all living cells
respiration
Put the following in order:
a. animals eat plants to get energy
b. plants absorb sunlight
c. plants use chemical energy to make
organic compounds
d. light from the sun reaches Earth
e. plants convert sunlight to chemical
energy
d b e c a
Photosynthesis or Respiration?
- light is required
photosynthesis
What is an organism called that uses
sunlight and inorganic molecules to
produce organic molecules?
autotroph
FINAL QUESTION
Good Luck!
What is the process of splitting water
called?
photolysis
What was the plant that was first used
in experiments in the 1700’s that led
to the discovery of photosynthesis?
The mint leaf
