Another name for adenosine
triphosphate
2
What is ATP?
3
This is where the energy is stored
within an ATP molecule
4
What is in the phosphatephosphate bonds?
5
When it is needed by the body,
ATP gets broken down to this
molecule
6
What is ADP (adenosine
diphosphate)?
7
This is the reason that ATP can be
broken down so easily
8
What is it takes a tremendous
amount of energy to force the
three phosphates together?
9
Because of this, the cell is
relieved of having to store all of
the ATP it needs
10
What is there are free phosphates
in the body and the molecule
recycles itself?
11
This is the process that plants use
to trap the sun’s energy to make
their own food
12
What is photosynthesis?
13
This is the main energy-trapping
pigment within the chloroplast
14
What is chlorophyll?
15
The light-dependent reactions
take place here
16
What is in the thylakoid
membranes of the chloroplast?
17
These are the two high-energy
molecules produced in the lightdependent (light reactions) that
are used to make glucose in the
light-independent (dark
reactions)?
18
What are ATP and NADPH?
19
Photolysis is necessary to replace
electrons within the chlorophyll.
Name the products of photolysis
20
What are 2 H+ ions, 2 electrons,
and ½ molecule of oxygen gas?
21
This is another name for the
light-independent reactions of
photosynthesis
22
What is the Calvin Cycle?
23
This gas starts the lightindependent reactions of
photosynthesis
24
What is CO2?
25
Two of these molecules leave the
Calvin cycle and help make
glucose for the cell
26
What is G3P?
27
This enzyme converts the 3carbon molecule G3P back into
the 5-carbon molecule RuBP to
continue the Calvin cycle
28
What is rubisco?
29
It takes this many rounds of
the Calvin cycle to produce
one glucose for the cell
30
What is 6?
31
This is the reason that plants
contain different types of
pigments
32
What is that different pigments
absorb varying wavelengths of
light?
33
During the light dependent phase,
light energy is converted into this
type of energy in the chlorphyll
34
What is chemical?
35
This structure within a plant cell
allows for gas exchange
36
What is the stomata?
37
This is the name of the process in the
light reactions where H+ ions are
pumped across the membrane to
produce energy for the plant cell
during photosynthesis
38
What is chemiosmosis?
39
These are the names of the lightabsorbing molecules within the
cell membrane during the light
reactions of photosynthesis
(Hint: There are two of them)
40
What are Photosystem II and
Photosystem I?
41
Plants are categorized as this type
of organism, which can produce
its own food
42
What is an autotroph?
43
These are the products of
photosynthesis
44
What are glucose and oxygen?
45
This enzyme in the light reactions
pumps H+ ions across the
membrane and converts ADP into
ATP
(Remember: Enzymes typically
end in –ase)
46
What is ATP synthase?
47
This is the water-carrying tissue
of the plant
48
What is the xylem?
49
This male part of the flower
contains the pollen
50
What is the stamen?
51
