Oriole IB Photosynth

photosynthesis vocab & process

TermDefinition
ATP energy currency of living cells; produced during PS2 and used during step 3 to make glucose
CALVIN CYCLE third step/stage of photosynthesis; uses energy from ATP & NADPH to convert CO2 into glucose
CARBON DIOXIDE atmospheric gas that attaches to RuBP in step 3 so that G3P (PGAL) can be formed and then made into glucose
CHLOROPHYLL green pigment found in chloroplasts; absorbs light and transfers energy to ATP & NADPH in steps 1 & 2
CHLOROPLAST plant cell organelle that performs photosynthesis so that glucose can be made from CO2 & water
G3P produced during step 3 of photosynthesis and is used to make glucose and re-make RuBP
GLUCOSE six-carbon sugar produced from G3P (PGAL) during step 3 of photosynthesis
GRANA stack of thylakoids found in chloroplasts that contain chlorophyll for photosynthesis
LIGHT ENERGY absorbed by chlorophyll in steps 1 & 2 and transformed into stored energy as ATP & NADPH
NADPH high-energy compound produced in step 2 and used by step 3 to make G3P (and then glucose)
OXYGEN given off by plants during step 1 as waste; taken in by animals during respiration (breathing)
WATER broken apart by plants in step 1 for making high-energy electrons and giving off oxygen
PHOTOSYSTEM 1 second step/stage of photosynthesis that absorbs light energy in order to make NADPH for step 3
PHOTOSYSTEM 2 first step/stage of photosynthesis that absorbs photons to make ATP so that glucose can be made in step 3
RuBP used in step 3 to collect CO2 so that glucose can be made; recylced over and over again in this stage
STROMA gel-like fluid inside chloroplast surrounding thylakoids; water is stored here so that photosynthesis can occur
THYLAKOID structure within the chloroplast; membrane contains chlorophyll and other molecules to carry out 3 steps of photosynthesis
PHOTOSYNTHESIS process carried out by plants; consists of three steps or stages; used to store absorbed light energy in bonds of glucose
PHOTONS packets of light energy that behave as both particles and waves; are absorbed and transformed during photosynthesis
