light dependent reaction

what is the equation / reaction of photosynthesis ?

6CO2 + 6H2O → C6 H12 O6 + 6O2

what does the term Photolysis means ?

photosystem II contains enzyme which split water into the presence the of light.

what is the reaction / equation of split of water ?

2H2O → 2H2 + O2 + 2 e- w

what is being released during photolysis ?

Electrons are released to replace those cost in photosystem II

what is the process of light dependent reaction ? Stage 1 - 2

Light hits the photosystem II and it excites the electrons to a higher level

Electrons passes along the electron transport chain ( protein within the thylakoids membrane ) in a series of redox reaction.

what is the process of light dependent reaction ? Stage 3 - 4

Electron loses energy as they pass down the chain. This energy is used to pump H+ into thylakoids lumen from the stroma.

Due to the high concentration of H+ in the lumen , H+ diffuse back to the stroma via ATP synthase. This generates ATP.

what is oilrig means ?

oxidation is lose , reduction is gain

what does photophosphorylation means ?

When phosphate group is added to a molecule, Generation of ATP from ADP + inorganic phosphate in the presence of light.

what are the 2 types of photophosphorylation

Non cyclic and cyclic

which photosystem is for non cyclic ?

both photosystem I and II

which photosystem is for cyclic ?

only photosystem I

Cyclic photophosphorylation only colours in photosystem I what happen to the electrons ?

The excites electrons pass through electron carriers but some passed back to the chlorophyll hence cyclic.

As electrons pass between carriers, energy is lost + used to phosphorylate ADP + inorganic phosphate → ATP

what happens to the electron in the non cyclic ?

The coenzyme ( NADP ) acts as the final electron acceptor , becoming reduced to NADPH.

NADP → NADP + →( electron acceptor ) → NADPH
