Before moving to P700, electrons activated by photons striking P680 provide energy for
pumping protons into the space shown as lumens in the illustration. Entering into the
end of the system, the electrons expelled from P700 transform NAPD+ into NAPDH.
Throughout the course of the process electrons derived from water molecules con-
stantly replace the electrons lost from P680. This process is shown in greater detail
in the diagrams below.
el and produced in this stage will be employed in the dark phase when
the fundamental processes are carried out—and this system, a marvel of
design, will thus be completed.
