The protein complexes do more You mentioned ATP before,
than transport electrons in a but I think this is the first
predetermined order. time I've heard of NADPH...
a molecule called NADPH
is synthesized along the
way, and ATP is created at
the end of the chain.
NADPH consists Proton
of an electron and a
proton (hydrogen ion)
adhered to a molecule
called a hydrogen
acceptor. It is created
by NADPH reductase.
Tionshser'eem! NADPH can be thought of as
a temporary storehouse for
an electron and a proton, which
are required by the carbon
dioxide fixation reaction we
talked about earlier.*
* In other words, NADP + is "reduced," and NADPH is created. (See page 37 for an explanation of reduction.)
The energy that’s generated is Now let's look
just a "flow of electrons," and, in that at the way ATP is
sense, it's just like the electricity you use created by photo
phosphorylation!

The electron transport chain also creates
a "flow of electrons." Substances like ATP are
synthesized by this electron flow.
