A RuBP pathways which synthesize large molecules from smaller ones B Stroma photosynthesis is considered to be this type of reaction because it requires energy from the sun to occur C Light- Dependent Reactions the structure in which chlorophyll is contained the Calvin Cycle takes place in this part of D Light-Independent Reactions the chloroplast ATP and NADPH are the two main products E Anabolic G 3 P is the main product F Calvin Cycle electrons that leave the reaction center of this molecule are replaced by electrons generated by the splitting of H 2 O G Oxygen electrons that leave the reaction center of this molecule are replaced by the electron passed H Thylakoid on from the ETC of PSII the most important by-product of I Chemiosmosis photosynthesis a series of membrane-embedded proteins through which high energy electrons are transferred K. Photosystem II the movement of hydrogen ions down a gradient L. Photosystem I the protein through which hydrogen ions are passed as they enter the stroma M G 3 P three-step cycle that does not require the excitation of electrons to initiate reactions N Electron transport chain molecule used to "fix" carbon dioxide O Endothermic used to make glucose.
