C4 Pathway a carbon-fixing process in which carbon dioxide is bound to a compound to form a four carbon intermediate
Stomata openings in a leaf or a stem of a plant that enable gas exchange to occur
carbon fibers the synthesis of organic compounds from carbon dioxide such as in photosynthesis
Calvin cycle a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
chemiosmosis in chloroplast & mitochondrion a process which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP
electron transport chain a series o molecules found in the inner membranes of mitochondria & chloroplast through which electrons pass in process that causes protons to build up on one side of the cell membrane
primary electron acceotor in chloroplast an acceptor of electrons lost from chlorophyll found in the thylakoid membrane
photosystem in the thylakoid membranes of chloroplast, a cluster of chlorophyll. 3 other pigment that harvest light energy for the light reactions of photosynthesis
cartenoid class of pigments that are present mostly in plants during photosynthesis
chlorophyll gives plants green color, reacts with sunlight carbon dioxide and water to make carbohydrates
pigment substance that gives another substance/mixture color
stroma the solution in plants that surrounds thylakoids in chloroplast
granum a stack of thylakoids in chloroplast
thylakoid found within chloroplast, contains components for photosynthesis
chloroplast organelle where photosynthesis occurs
light reactions the reactions in photosynthesis which are caused by the absorption of light in photosynthesis with passage of electrons production of NADPH and oxygen gas. synthesis of ATP through chemiosmosis
heterotroph an organism that obtains organic food molecules by eating other organisms
photosynthesis The process by which plants, algae, some bacteria use sunlight, carbon dioxide & water to produce carbohydrates and oxygen
