description of photosynthesis and tell me if it is accurate.
Note that this is very basic and probably simplified to an
extreme (especially the calvin cycle as no enzymes are
mentioned.)  As visible spectra comes into contact with the
light harvesting units of the chloroplast’s thylakoid membrane
(PSI, PSII,) quantum’s of energy are absorbed and electrons on
ground state are thus excited. Instead of returning to ground
state, electron transport molecules made of lipids or proteins
that are adjacent to the unit of pigment molecules attract the
electron. It is important to note that the flow of electrons is
non-cyclic; meaning they flow in one direction and do not return
to where they originated from. This is because each carrier
molecule has a greater affinity for electrons than its
neighboring molecule; meaning electrons travel down the
transport chain starting with the oxidation of H2O and
