Photosynthesis!!!!

The reaction begins with the sun,Which releases energy necessary for the process of Photosynthesis.

Sunrays

The sunrays hit a plant which activateThe chlorophyll located in the chloroplasts

Chloroplast

The chloroplasts, once activatedBy the sun, release electronsFull of energy.

Electrons

Water is splitBy the released electrons. The oxygenMolecules are then released (which is what we breath).

The rest of the hydrogen is set aside and creates a H+ (again using electron energy).

The now low powered electronsReturn to chlorophyll andare ready to start the processall over again.

Now its time for……………..

THE DARK CYCLE!!!!!!!!!

YAY

NADPH2

NADPH2 looses its H+ to carbon dioxide, the leftoverNADP is recycled to continue the light cycle again.The same happens to ATP which becomes ADP and isRecycled

The CO2 combines with RUBP and through manyComplex steps, becomes PGAL. This cycle repeats6 times.

THIS HAPPENS6 TIMES!!!!

All this comes together in the last step when theHydrogen from the NADPH comes in….
