photosynthesis vocab & process
Term | Definition |
---|---|
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 |
