16
Q

antenna complex

A

complex of hundreds of accessory pigments energy transferred from antenna complex to the reaction center

17
Q

reaction center

A

electrons here are excited on chlorophyll a molecules energy transferred to a final electron acceptor these electrons are replaced by electrons from water

18
Q

primary photoevent

A

pigment molecule captures energy from a photon in the antenna center

19
Q

charge separation

A

energy is moved to reaction center, excited electron is transferred to a final electron accepor

20
Q

electron transport

A

electrons carried by NADPH

21
Q

CHEMIOSMOSIS
