The first, most immediate, the thing that happens when light strikes a chlorophyll molecule - A.Electrons are energized.
- In light-dependent reactions, light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule.
- These electrons jump up to higher energy levels; they have absorbed or captured, and now carry, that energy.
- A photon of light hits chlorophyll, causing an electron to be energized.
- The free-electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.
