Studied by 23 peopleATP
AKA adenosine triphosphate- adenine, ribose, and 3 phosphate groups
Anabolic
small molecules combined
autotroph
produce their own food(glucose)
carotenoids
pigments in plants, algae, & photosynthesis bacteria
chemiosmosis
light energy to chemical energy (ATP) (light-dependent)
chlorphyll
green pigment reflected in plants
endergonic
reactions that absorb energy
endothermic
reactions that require heat
granum
stack of thylakoids that contain chlorphyll
photophosphorylation
free phosphate can be re-attached to ADP reforming ATP
photorespiration
occurs on hot, dry, bright days
photorespiration
what occurs when the stomata is close?
photorespiration
what is the fixation of O2?
photorespiration
what produces 2-C molecules?
stomata
pores in a plant's cuticle (water vaport and gases(CO2 and O2) are exchanged between the plant & atmosphere
thylakoid
membranous disks of lamellae within plant chloroplasts
chemical formula for photosynthesis
6 C02 + 6H20------C6H12O6 + 6 O2
stroma
tiny openings on epidermis of leaves
water vapor and oxygen
gases that exit the stomata
carbon dioxide
gas that enter the stomata
chlorplast
photosynthesis occurs in the
chlorphyll pigments are reduced
leaves change colors because
blue-420 and red-660
what wavelengths make plants the color they are?
boarden the range of light that can be absorbed by a plant
what do accessory/secondary pigments do?
accessory/secondary pigments
what are chlorphyll b, carenotoids, xanthophyll, anthocyanin, phycoerythrin, and phycocyanin?
chlorphyll b
what transmits green light and absorbs blue and red light?
carenotoids
what reflects orange, yellow, and red light waves?
xanthophyll
what makes leaves turn yellow in the fall?
anthocyanin
what absorbs blue-green light?
the sun
what is the energy for all life on Earth?
light reactions
light energy to make two molecules for the next stage of photosynthesis
ATP and NADPH
what is the result of a light reaction?
thylakoid membrane
where is a light reaction located?
dark reactions
carbon-fixing reaction
glucose
what is the end product of a dark reaction?
stroma
where is a dark reaction located?
stroma
where is the calvin cycle located?
glucose
what is the final product of the calvin cycle?
C3 pathway
what is the calvin cycle known as?
C3 plants
what type of plant is in hot and moist environments, is in 15% of plants, and makes 4-carbon sugar?
C4 plants
what type of plants avoid photorespiration, uses PEP during carbon fixation(fixes carbon dioxide into a four-carbon molecule called malate)
CAM plants
what type of plants lives in hot, dry environments, in 5% of plants, and stomata is closed during day and open during night?
light reaction
what reaction occurs during the day?
calvin cycle
what reaction occurs during the night?
photorespiration
what occurs on hot, dry bright days, stomata is close, has a fixation of O2, produces no sugar or ATP?
oxygen
Which product is released during the light-dependent reactions?
to make glucose
What is the purpose of photosynthesis?
split water into H and O
What is light energy used to do?
excess water being released from leaves
what is transpiration?
carbon dioxide
what is the gas we breathe out that plants use for photosynthesis?
to produce NADPH and ATP
what is primary function of light dependent reactions?
