What is the name of the molecule that absorbs light in the
chloroplasts? -
ANSWER -Chlorophyll (absorbs light to energize
molecules)
What is the goal of the light reactions of photosynthesis? -
ANSWER -To use
sunlight to make usable
energy
What happens in Photosystem II? - ANSWER -Pigments absorb
photons and move it from pigment to pigment until it gets to
P680. P680 gets an electron from a water molecule by splitting
the water into oxygen and hydrogen ions (H+). The photon
excites the electron, moving the high energy electron up. As
the electron trvaels from protein to protein in the ETC, its
energy gets lower and lower. The energy that the electron givs
up is absorbed by ATP.
,What is P680 and what is its function? - ANSWER -A special pair
of chlorophyll
molecules that is found at the center of PS2. It is the center
where water is split
and the elctron crossover
occurs
Why is water split in Photosystem II? - ANSWER -So that
P680 can get an
electron from the water
molecule
What is donated to the electron transport chain from
Photosystem II? -
ANSWER -A high energy
electron
What is the function of the electron transport chain between
Photosystem II and
Photosystem I? - ANSWER -It creates ATP from the energy
that high energy
electrons lose because the ATP absorbs that energy. Also to link
electrons from
PS2 to
PS1
How is ATP made in the light reactions? - ANSWER -By
absorption of energy
, that high energy electrons lose in
the ETC
Why isn't water split in Photosystem I? - ANSWER -In PS1, the
photon enters the same way it did in PS2. But this time, the
electron is provided by PS2 rather than needing to split water.
What is difference between cyclic and non-cyclic energy
production in the light reactions? - ANSWER -AS long as non-
cyclic production has water, it can keep PS2 going in a cycle
because it provides the electrons necessary for the light
reactions.
Why do we need both PS2 and PS1? - ANSWER -We need both
because PS1
would not work without PS2's ability to get the
cycle going.
Centrosome - ANSWER -A structure in animal cells containing
centrioles from
which the spindle fibers
develop.
What is the primary goal of the Calvin Cycle? - ANSWER -To
make organic
molecules
