ET dynamics in photosystem I
●Elementary steps are almost unresolvable,
In the case of very intact PSI RC
●They become time-resolved with the help of
antenna Chl removal,
quinone reconstitution and
selective
excitation
●Forward ETs are optimized to be fastest
for the edge-to-edge
distance
between ET donor and
acceptor molecules
●To achieve the high reduction ability
reorganization energy is adjusted to be equal to the
free
energy gap of the ET
