antenna complex

[an′ten·ə ‚käm‚pleks]
(cell and molecular biology)
A complex of protein molecules found in the thylakoid membrane of chloroplasts that captures and transfers light energy to the photochemical reaction center.

For instance, invisible rods could be used as supports for a miniature antenna complex connecting two optical chips.
PSII is a complicated complex comprising outer light-harvesting complex (LHCII), core antenna complex (including CP43 and CP47), reactive center complex (RC) and Manganese cluster, and its components are so located and assigned as to ensure the quick and efficient energy and electron transfers.
It is generally believed that the core antenna complex CP43 and CP47 receive energy from outer LHCII system and assistant antennas, and then transfer the energy to RC complex to complete the energy transfer.

several students, depending on the size of the class, designated as chlorophylls a and b, and carotenes and xanthophylls in the antenna complex
We meet the two chlorophyll a molecules in the reaction center, surrounded by the antenna complex pigments, and other characters in the play.
2 There are the antenna complex pigments to the rescue
The sun shines light on various points in the class, eventually hitting one of the pigments in the antenna complex.
3 When an antenna complex pigment in plain sight Absorbs a photon of light,
8 Another photon of light and the antenna complex is excited.
They will then examine the pigments' photophysics, appreciating (1) the efficient absorption of visible sunlight accomplished by plant pigments and (2) the energy- and electron-transfer processes between the antenna complex and the reaction center and between the reaction center and the primary electron acceptor.
They fear that it poses a health threat and complain that the huge antenna complex has grown out of sync with the gated neighborhood of million-dollar mansions, horse paddocks and private golf links.
