Light Photosystems Dependent Reactions Excitation Energy Step Process

In light-dependent reactions, photosystems are classified by their maximum absorption wavelengths (PSII at 680 nm, PSI at 700 nm). Light energy excites delocalized electrons within the photosystems, which are then transferred to carrier molecules in the thylakoid membrane.
