|
Photosynthesis
|
plants, algae and several other groups of bacteria can harvest the radiant energy of the sunlight and then use it to power the synthesis of organic carbon compounds from CO2
|
|
|
Light reactions
|
capture the energy from light and convert it to chemical energy in the form of ATP
|
|
|
Light independent / Dark Reactions
|
capture the energy from light and use that energy to synthesize organic carbon compounds
|
|
|
carbon fixation
|
the processes used to convert carbon carbon dioxide into organic compounds
|
|
|
Chlorophylls
|
found in plants, algae and a group of bacteria called cyanobacteria. the photosynthetic processes of organisms that employ chlorophylls are oxygenic meaning they evolve oxygen
|
|
|
bacteriochorophylls
|
are found in 2 groups of bacteria : purple photosynthetic bacteria and green photosynthetic baceria
bacteriophylls- absorb wavelengths not absorbed by chorlophylls - therefore they can grow in habitats where other photosynthetic cannot ANOXYGENIC - meaning they do not evolve oxygen |
|
|
Accessory pigments
|
carotenoids and phycobilians
they increase the efficency of light capture by absorbing wavelengths of light NOT absorbed by choropyll |
|
|
photosystems
|
photosynthetic systems are located together in the photosystems - which specialize in capturing light
|
|
|
Reaction center pigments
|
reaction center pigments function as the electron donor in the photosynthetic process; in response to excitation by radient eergy, the molecule emits an electron which is then passed to an electron transport chain similiar to that used in respiration
|
|
|
antenna pigments
|
make up what is called the antenna complex, which acts as a funnel capturing energy of light and then transfering it to the reaction center pigment
