LIGHT IS ABSORBED THROUGH CHLOROPLASTS INTO THE PHOTOSYSTEM
THE PHOTON IS PASSED TO OTHER CHLOROPHYLL MOLECULES ENDING UP IN A CHLOROPHYLL IN THE REACTION CENTER
THE ENERGY CAUSES AN ELECTRON TO LEAVE THE MOLECULE AND BE TRANSFERRED TO A PRIMARY ELECTRON ACCEPTOR
THE TRANSFERRED ELECTRON TRAVELS THROUGH PROTEINS. THE ELECTRON'S ENERGY IS USED TO PUMP HYDROGEN INTO THE INTERIOR OF THE THYLAKOID. A PIGMENT IN PHOTOSYSTEM I ACCEPTS THE ELECTRON WHICH RESULTS IN THE FORMATION OF NADPH USED TO START THE CALVIN CYCLE
THE ENERGY IS THEN USED TO ASSEMBLE SUGAR MOLECULES FROM CARBON DIOXIDE
light-independent reaction
Calvin Cycle
: using energy from the beginning of photosynthesis, the cycle takes CO2 from around it to build carbohydrates. CO2 is combined with RuBP which creates 6-carbon compounds. These compounds are broken into two 3-carbon compounds which, using ATP and NADPH, are converted into G3P. One G3P becomes a part of the carbohydrate while the other stays in the cycle
IN THE FIRST STAGE OF THE CALVIN CYCLE RUBISCO BRINGS CO2 INTO AN ORGANIC MOLECULE.
IN STAGE TWO THE ORGANIC MOLECULE IS REDUCED
IN STAGE THREE RUBP IS PRODUCED AGAIN SO THAT THE CYCLE CAN KEEP GOING FROM THE BEGINNING
3 ATP IS PUT IN AND 3 ADP IS RELEASED
6 NADPH GOES IN AND 6 NADP+ + H+ IS RELEASED
SUGAR IS RELEASED
6 ATP GOES IN AND 6 ADP IS RELEASED
3 MOLECULES OF CO2 ARE ENTERED
WATER IS SPLIT TO RELEASE AN ELECTRON TO REPLACE THE ONE THAT LEFT. THIS SPLIT ALSO FORMS OXYGEN AND HYDROGEN
light-dependent reactions
: pigment molecules absorb the energy from sunlight. Then, a photon hits photosystem II to start photosynthesis. Energy goes through the electron transport chain which puts hydrogen in the thylakoid space creating an electrochemical gradient. The ons go through ATP into the stroma to create ATP. Photosystem I takes in a second photon which forms NADPH
Photosynthesis Equation
carbon dioxide + water
sunlight
sugar + oxygen
