photosynthesis notes

chlorophyll

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
