Electron transport chain
Of protons, neutrons or electrons, the electrons are the only ones at the outside to be transferred between atoms.
their kinetic energy is transferred to the electrons of the neighboring atoms and kinetic energy is conserved as most molecular collisions are elastic.
Without a bit more guidance on the specific topic, it's hard to know how to answer. You might say that energy is generally transferred and not destroyed, or that in chemistry electrons are transferred but not destroyed, or atoms in chemical reactions, or ...
Electrons are transferred in any protonation or deprotonation. Electrons are also transferred in redox (oxidation-reduction) reactions.
Some of the electrons become excited. means that they have comparatively more energy. the flow of energy takes place through these excited electrons. these are transferred form the reaction center chlorophyll to the primary electron acceptors.

Electron transport chain
Excited electrons are transferred to an electron transport chain.
a cation gains electrons and has a positive charge while a anion loses electrons and has a negative charge
When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high-energy electrons make photosynthesis work
NADH
It means conversion of energy from one form to another.Energy can be easily transferred.
Of protons, neutrons or electrons, the electrons are the only ones at the outside to be transferred between atoms.
