PSII will absorb red light, and PSI will absorb far-red light. Although photosynthetic activity will be detected when the photosystems are exposed to either red or far-red light, the photosynthetic activity will be the greatest when plants are exposed to both … See more Photosystems are functional and structural units of protein complexes involved in photosynthesis. Together they carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of See more Reaction centers are multi-protein complexes found within the thylakoid membrane. At the heart of a photosystem lies the reaction center, which is an enzyme that uses light to reduce and oxidize molecules (give off and take … See more In intense light, plants use various mechanisms to prevent damage to their photosystems. They are able to release some light energy … See more • Light reaction • Photoinhibition • Photosynthetic reaction centre See more A reaction center comprises several (about 25-30) protein subunits, which provide a scaffold for a series of cofactors.
