The movement of excited electrons in noncyclic photophosphorylation is

The movement of excited electrons in noncyclic photophosphorylation is initially uphill where photosystem II the reaction centre chlorophyll ‘a’ absorbs 680nm wavelength of red light causing
electrons to become excited and jump into the orbit farther from the atomic nucleus following that the movement of electrons is downhill, in terms of an oxidation-reduction or redox potential scale.
