Question

What happens to electrons when pigments in Photosystem ll absorb light?

Answer 1

“Each time a pigment molecule absorbs light energy, one of the pigment’s electrons gains energy- the electron is raised from a low energy ‘ground state’ to a high energy ‘excited state’”

Answer 2

Within the thylakoid membrane, chlorophyll and other molecules are arranged in clusters called photosystems (Figure 8-8). ... Each time a pigment molecule absorbs light energy, one of the pigment's electrons gains energy—the electron is raised from a low-energy "ground state" to a high-energy "excited state."
