3. Fill in the blanks outlining the steps of the LIGHT DEPENDENT REACTION of photosynthesis.
Then, with a sentence, explain the overall purpose of this reaction.
2. An
1. A
of light is absorbed by Photosystem II (a blob of chlorophyll) in the
thylakoid
membrane.
from chlorophyll becomes excited and moves to a higher energy
level.
3. The high energy electron passes through the
and a small amount of ATP is made from the electron's extra energy. This
Calvin
ATP will be used later to power the Dark Reaction (
cycle)
4. The electron enters Photosystem I, another blob of
Light
again strikes the Photosystem (chlorophyll), and the electron is again excited.
5. The high energy electron is absorbed by
and NADPH is made. NAD+
is an
bank, and holds on to electrons until they are needed.
6. To replace the ORIGINAL electron from Photosystem II, a molecule of
is split, and
is made as a waste product.
7. The light reaction is over, and the products are ATP, NADPH, and
The purpose of the light reaction is to
