7968963409rubiscomost abundant enzyme; fixes CO2 to RuBP in C3 plants11
7968965087NADP+oxidizing agent that can carry 2 electrons and a H+12
7968967442bundle sheathlocation of the CO2 fixation in C4 plants13
7968967859PEP carboxylasehas no affinity for O2 and fixes CO2 in C4 and CAM plants14

7968970715Glyceraldehyde-3-Phosphatesugar product from photosynthesis16
7968972336photona 'packet' a light energy17
7968973890photophosphorylationthe use of light energy to power the production of ATP18
7968974418photoexcitationwhen an electron captures a photon of light and enters the excited stage19
7968976159plasmodesmatajunctions joining the cytoplasm of neighboring cells in plants20
7968977524diffusionprocess by which O2 and CO2 move through the plant cells21
7968979469palisade layertall, boxy cells that are tightly arranged and are densely population with chloroplasts for maximum photosynthesis production22
7968983443Krantzstructure of the leaf components in a C4 plant23
7968984964transpirationprocess of moving water from roots to leaves and out of the plant24
7973096659cytochrome complexuses the energy from the e' to move H+ ions through the membrane25
7973104268photorespirationoccurs when the stomata close. CO2 is limited and therefore 02 is bound to RuBP. Plants loses approx 50% organic matter26
