BioCoach Activity Concept 8: Cooperation of the Light Reactions and the Calvin Cycle

Photosynthesis Calvin Cycle - SlideShare

This process is called chemiosmosis, or specifically for photosynthesis it's called photophosphorylation.
The harvested energy from the ATP synthase is then used to pack an inorganic phosphate onto ADP, creating ATP which is one of the major forms of cellular energy.
Another photon then hits photosystem I.

Eventhough, dependent reactions don't specifially need the Calvin cycle to proceed, the plant needs sugars in order to continue photosynthesizing.

Photosynthesis – the light dependent stage and Calvin cycle

This is what pulls electrons into the electron transport chain.

2H2O---> 4H + O2+ 4e-
While P680 undergoes oxidation, a process called photolysis occurs.

The cycle of photosynthesis and respiration maintains the balance of oxygen and carbon dioxide

This requires the phosphate from three different ATP molecules.
ATP-Pi---> ADP
Light Independent Reactions:
The Calvin Cycle
The result of light dependent reactions are oxygen, NADPH, and ATP.
Chlorophyll is found in both photosystems and is primarily green.

The first stable product of the Calvin Cycle is phosphoglycerate (PGA), a 3-C chemical
