Many Antenna Complexes Have a common structural motif In all eukaryotic photosynthetic organisms that contain both chlorophyll a and chlorophyll b, the most abundant antenna proteins are members of a large family of structurally related proteins, some of these proteins are associated with PSI and PSII such as LHCI and LHCII , Select the incorrect one regarding LHC complexes;

#Unit 6. System Physiology – Plant
  1. Photosystem I with the LHC I trimer in thylakoid membrane are predominantly higher in comparison to PSII with the LHC II dimer
  2. The structure of one of the LHCII proteins has been determined it contains three α-helical regions and binds about 15 chlorophyll a and b molecules, as well as a few carotenoids
  3. Light absorbed by carotenoids or chlorophyll b in the LHC proteins is rapidly transferred to chlorophyll a and then to other antenna pigments that are intimately associated with the reaction centre.
  4. Photosystem II are associated with light-harvesting complex II (LHCII) proteins while photosystem I are associated with light-harvesting complex I (LHCI) proteins These antenna complexes are also known as chlorophyll a/b antenna proteins
