what is the formula for photosynthesis?
|
6h20 +6co2=c6h12o6=o2
|
|
light is
|
photons
|
|
what color algae grows deepest? why?
|
red, red light weakest, can't reach low, the algae, absorbs all other light but red, reflects red.
|
|
rainbow is an example of ______light
|
refracted
|
|
unit symbol for wave length
|
lambda
|
|
wavelength is
|
crest to crest of light waves
|
|
frequency is
|
# of waves per unit time
|
|
chlorophyll does what
|
absorbs energy- uses it to kick electrons up
|
|
why do leaves turn red?
|
no chloroplasts
|
|
how do you give E back to Mg?
|
split the water, two pos. H's given back.
|
|
photons pump what?
|
H
|
|
chlorophylls absorb_______, not _________, that's why they are green
|
absorb red/orange, violet/blue, not green. reflect green.
|
|
which chlorophyll is used directly in photosynthesis?
|
a
|
|
calvin cycle aka
|
dark phase
|
|
what is the calvin cycle in reverse?
|
Glycolysis
|
|
calvin cycle 3 and 6 times
|
pgal and sugar
|
|
in the dark phase, why add a P?
|
to energise the molecue.
|
|
what is the purpose of the light phases?
|
to make energy and material for the dark phase
|
|
in non cyclic photophos. what happens instead of the H going back to the magnesium?
|
makes an NADPH
|
|
food thru
water thru |
phloem
xylem veins!!! |
|
what type of algae did melvin calvin use to figure out the calvin cycle
|
chlorella
|
|
what did melvin plunge the chlorella into ti stop the photosynthesis?
|
boiling alcohol
|
|
after calvin put the algae into a centrifuge, got out the clear material, couldn't read rf values cause clear, what did he do
|
added carbon 14, at the beginning.
|
|
added carbon 14, then what?
|
did a chromatogram ,put the material on x-ray film , compared rf values.
|
|
differences between light and dark phase?
|
energy and raw materials vs. sugar/food
|
|
differences betweencyclic and non
|
cyclic-atp only
non-E not return to source |
|
chlorophyll a does___
|
uses light energy from accessory pigments. has the Mg, uses it to kick off photosynth. kicks up EE
|
|
where does the light phase occur?
|
thylakoid membrane
|
|
what does rf refer to
|
ee
