Q

light reaction produce no

18
Q

In photosynthesis sugars are imported because they convert light energy to chemical energy in the form of 2 compounds:

A

ATP and NADPH

19
Q

These 2 compounds are used to provide the energy for the Calvin Cycle

A

ATP and NADPH

20
Q

Calvin cycle begins by incorporating____from the air into organic molecules already present in the chloroplast

A

Carbon Dioxide

21
Q

The Calvin cylce makes sugar witht the help of _____ and _____ which are produced by light reactions

A

ATP and NADPH

22
Q

In photosynthesis light reaction occur in the

A

thylakoid of the chloroplast

23
Q

in photosynthesis the calvin cycle occurs in the

24
Q

which light colors work best for photosynthesis

A

Red or Blue

25
When a photon(burst of light) hits an electron, it goes to an "excited state" which is unstable. When the electron drops back down to the ground state orbital, excess energy is released as
Florescence
26
Calvin Cycle: Anabolic or catabolic
Anabolic
27
Calvin Cylcle: Consumes energy or produces energy
Consuemes energy--Endergonic
28
Carbon enters Calvin Cycle in form of carbon dioxide and leaves in the form of
sugar
29
carbohydrate produced directly from the Calvin Cycle is actually not glucose, but it is a
3 Carbon Sugar called glyceraldenyde-3-phosphate (G3P)
30
to synthesize 1 glucose molecule, the Calvin cycle uses how many molecules of carbon dioxide, AT, and NADPH?
6-Carbon Dioxide 18-ATP 12-NADPH
31
A cell can have up to how many chloroplast
30-40
32
Photosythesis=
light reaction
33
Calvin Cycle=
synthesis
34
During what cycle are 10 million molecules of ATP consumed and regenerated
ATP cycle
35
What is the shuttling of inorganic phosphate and energy
ATP cycle
36
this process couples the cells exergonic reactions to the cells endergonic reactions
ATP cycle
37
a chemical reaction that has a positive delta G is correctly described as
endergonic
38
which process in eukaryotic cells will proceed normally whether oxygen is present or absent
Gylcoysis
39
How many oxygen molecules are required when 2 molecules of glucose are completely oxidized via aerobic respiration
12
40
where is most of the ATP generated during cellular respiration
oxidative phosphorylation
41
leaf looks green because
absorbing voilet-blue and red light while reflecting the green light
