Studied by 4 peoplechlorophyll
any of a group of green pigments found in photosynthetic organisms; there are four naturally occurring forms
photosystem
cluster of pigments in the thylakoid membrane
photosystem 2
the first photosystem in the thylakoid membrane
photosystem 1
the second photosystem in the thylakoid membrane
photosynthesis equation
6CO2 + 6H2O → C6H12O6 + 6O2
light reaction
the first stage of photosynthesis during which energy from light is used for the production of ATP and NADPH
calvin cycle step 1
carbon fixation
calvin cycle step 2
reduction
calvin cycle step 3
regeneration
light independent reaction
also known as calvin cycle, makes sugar from NADPH and ATP
electron transport chain (ETC)
electron is taken from ps2, releases energy, goes to next electron acceptor, til ps1, where all is released. makes ATP
NADP
picks up electrons from proteins
NADPH
NADP picks up a hydrogen, has energy within it.
Oxygen
byproduct of photosynthesis
CO2 reduction
a series of reactions turns RUBP into two three carbon sugars, PGA
carbon fixation
CO2 attaches to RUBP, a 5 carbon molecule.
PGA
the product of CO2 reduction
regeneration
ATP donates a molecule, becomes ADP, and becomes G3P
G3P
product of the carbon cycle
glucose
two G3P's are required to make
3 turns
one carbon cycle, expels one G3P
stroma
the area where loight dependent reactions take place
