front 8 does oxygen come from water or CO2 in basic photosynthesis? | back 8 WATER |
front 9 what does photosynthesis power? | back 9 the biosphere |
front 10 what does chloroplasts contain that give plants their green color? | back 10 chlorophyll, a green pigment |
front 11 is chlorophyll found in all plants? | back 11 NO. |
front 12 where is chlorophyll mainly found? | back 12 in the mesophyll layer |
front 13 what do plant leaves contain? | back 13 they contain stomata ( stoma plural ) |
front 14 what is the stomata | back 14 the openings for gas exchange |
front 15 what goes into the stoma? | back 15 CO2 |
front 16 what goes out of the stoma ? | back 16 O2 |
front 17 thylakoids | back 17 contains chlorophyll ( green pigment ) composed of thylakoid membrane surrounding thylakoid lumin |
front 18 what are stacks of thylakoid called? | back 18 granum |
front 19 Stroma | back 19 liquidy material surrounding thylakoids |
front 20 what is inside the thylakoid membrane | back 20 thylakoid lumin |
front 21 what is the site of photo(light) reactions ? | back 21 thylakoid |
front 22 what is the site of light independent reactions or synthesis reactions? | back 22 the stroma |
front 23 where are pigments embedded ? | back 23 in the thylakoids membrane |
front 24 what is the main pigment ? | back 24 chlorophyll A |
front 25 what are accessory pigments? | back 25 chlorophyll B, carotenoids, xanthophyll, cyanins |
front 26 why is the thylakoids embedded in the membrane? | back 26 it is mostly all hydrocarbon |
front 27 porphyrin ring, also referred to as antenna complex | back 27 pigments shaped liked a kite. |
front 28 whats at the center of porphyrin ring? | back 28 a magnesium atom |
front 29 2 stages of photosynthesis reactions | back 29 photo(light) dependent and synthesis(light) independent |
front 30 photo ( light ) dependent reaction | back 30 occur in thylakoids, and produce ATP but used in light independent reactions to build carbohydrates, NADPH, and O2 |
front 31 type of light dependent reactions | back 31 non-cyclic phosphorylation |
front 32 phosphorylation | back 32 addition of phosphate |
front 33 photo | back 33 using light energy for the addition of phosphate group |
front 34 phosphorylation uses ATP to make energy from? | back 34 light |
front 35 synthesis ( light )independent reactions | back 35 , also referred to as the calvin cycle, and carbon fixation cycle. They use the energy from light reactions to build sugars |
front 36 2 ways to look at light energy | back 36 waves//particle |
front 37 Waves | back 37 theres short and long wavelengths, each one represents a different color |
front 38 wavelength | back 38 the distance from peak of 1 wave to the peak of another |
front 39 shorter waves have | back 39 MORE energy |
front 40 longer wavelengths have | back 40 LESS energy |
front 41 what is a particle | back 41 a photon, a particle of light |
front 42 Sun | back 42 a mixture of many wavelengths called white light, which is all of the wavelengths together |
front 43 what happens when light hits an object | back 43 some wavelengths are absorbed some are reflected |
front 44 white objects _ | back 44 reflect all wavelengths |
front 45 black objects _ | back 45 absorb all wavelengths |
front 46 photosynthetic pigment absorb.. | back 46 some light energy and reflect others |
front 47 why are plants green | back 47 they reflect green wavelengths |
front 48 what is not part of chloroplasts? | back 48 Matrix, its in the mitochondria |
front 49 what happens when a pigment absorbs light? | back 49 the energy in the photon is transferred to an electron |
front 50 what happens when a photon of light hits e- in the 2nd shell? | back 50 It gives in a lot more energy so the e- jumps to the higher shell |
front 51 what can happen when a high energy e- jumps to a higher shell? | back 51 It can either emit a less energetic photon OR the e- can get transfered to another molecule ( electron acceptor ) with exactly the right shell so that it stablizes the e- ( this all happens in the PIGMENT ) |
front 52 what happens when a photon of light hits magnesium ? | back 52 the electron ( e- ) in magnesium gets boosted to a higher energy level, then gets passed to e- acceptor molecule stabilizing the energy In that e- |
front 53 where do light reactions occur? | back 53 in the thylakoids membrane |
front 54 what is more likely to get hit with a photon? | back 54 chlorophyll B |
front 55 what sticks out of the thylakoids membrane? | back 55 the porphyrin ring |
front 56 what are 3 energy carriers of photosynthesis? | back 56 NADP+, NADH, and ATP |
front 57 NADP+ | back 57 similar to NAD+ just with P- ( photosynthesis ) |
front 58 NAD+ | back 58 gets reduced to NADH which carries high energy electrons to the calvin cycle |
front 59 ATP | back 59 also used as an energy source in the calvin cycle |
