A graph of the relative ability of a pigment to absorb different wavelengths of light
A graph that depicts the relative effectiveness of different wavelengths of radiation in driving a particular process.
Metabolism in which large molecules are constructed form small ones.
Bacterial photosynthesis that does not use water for an electron donor and does not release oxygen as a water product.
Complex enzyme, in the inner mitochondrial membrane, that permits protons to re-enter the mitochondria and synthesizes ATP using the released energy.
light harvesting pigment involved in bacterial photosynthesis
C3 (calvin/Benson) cycle
One type of stroma reaction
A set of metabolic reactos in which carbon dioxide is fixed temporarily into organic acids that are transported to bundle sheaths, where tehy release the carbon dioxide and C3 photosynthesis occurs
The synthesis of ATP from ADP and phosphate using the inergy of an osmotic gradient and a gradient of electrical charge; occurs in chloroplasts and mitochondria
pigment involved in capturing the light energy that drices photosynthesis; found in plants, algae, and cyanobacteria
Crassulacean acid metabolism (CAM)
A metaqbolism in which carbondioxide is absorbed at night and fixed temporarily into organic acids during daytime, the acids break down, carbon dioxide is released, and C3 photosynthesis occurs
cyclic electron transport
Teh flow of electrons form P700 back to plastoquinone in photosynthesis, such that there is proton pumping but no synthesis of NADPH
alternative: noncyclic electron transport
small electron carriers that contain iron
Electron transport chain
A series of electron carriers that transfer electrons form a donor which becomes oxidized to a receptor which becomes reduced
A mesure of disorder in a system
Formation of glucose form 3-phosphoglyceraldehyde
green house effect
the natural heating process of a planet, such as Earth, by which gases in the atmosphere trap thermal energy.
An organism that obtains its carbon form organic molecules not form carbon dioxide
light compensation point
The level of illumination at which photosynthetic fixation of carbon dioxide just matches respiratory loss.
light dependent reaction
set of reactions in photosynthesis that use energy from light to prduce ATP and NADPH
noncyclic electron transport
The flow of electrons from water to NADPH during the light-dependent reactions of photosynthesis
Alternative: cyclic electron transport
A measure of the number of electrons added to or removed from a molecule during an oxidation reduction reaction
The formation of ATP from ADP and phosphate, powered by energy released through respiration
often (but not always) contain a great deal oxygen
Oxygen is liberated as a waste product, oxidize water to reduce NADP and make NADPH, produces Oxygen and protons, light absorbed twice to span energy gap from H2O to NADP
a colorless gas (O3) soluble in alkalis and cold water
are photosynthsizers, use light for energy, and CO2 as carbon source
the light quanta, behave like particles
The process of generating ATP from ADP and phosphate by means of a proton-motive force generated by the thylakoid membrane of the chloroplast during the light reactions of photosynthesis
The oxidation of phosphoglycolate produced when RuBP carboxylase adds oxidation, not carbon dioxid, to RuBP
The pigments and electron carriers that transfer electrons from water to P700 to NADPH
The pigments and electron carriers that transfer electrons from P700 on photosystem 1
any material that absorbs certain wavelengths specifically and therefore has distinctive color is a ___________.
A copper-containing electron carrier.
A class of lipid-soluble electron carriers.
quality of sunlight
refers to the colors or wavelengths it contains
A partical of electromagnetic energy
A special cholorphyll a molecule actually involved in the transfer of electrons in photosynthesis
acceptor molecule reacts with a molecule of carbon dioxide
synonym for RuBP cargoxylase
RuBP carboxylase the enzyme in photosynthesis that carbonylates RuBP thus bringing carbon into the plant's metabollism
in plant photosynthesis the set of reactions that occur in stroma and are not direclty powered by light
alternative: light dependent reactions
The formation of ATP from ADP by having a phosphate group transferred to it form a substrate molecule.
