Front Back
organism that makes its own food using carbon from inorganic molecules such as CO2, and energy from the environment
chlorophyll a
main photosynthetic pigment in plants
organism that obtains energy and carbon from organic compounds assembled by other organisms
metabolic pathway by which most autotrophs capture light energy and use it to make sugars from CO2 and water
an organic molecule that can absorb light of certain wavelengths
distance between the crests of two successive waves of light
organelle of photosynthesis in plants and some protists
cluster of pigments and proteins that converts light energy to chemical energy in photosynthesis
semifluid matrix between the thylakoid membrane and the two outer membranes of a chloroplast
thylakoid membrane
a chloroplast's highly folded inner membrane system; forms a continuous compartment in the stroma
electron transfer phosphorylation
metabolic pathway in which electron flow through electron transfer chains sets up a hydrogen ion gradient that drives ATP formation
light-dependent reactions
metabolic pathway of photosynthesis that converts light energy to chemical energy of ATP and NADPH
light-independent reactions
metabolic pathway of photosynthesis that uses ATP and NADPH to assemble sugars from water and CO2
Calvin-Benson cycle
light-independent reactions of photosynthesis; cyclic pathway that forms glucose from CO2
carbon fixation
process by which carbon from an inorganic source such as carbon dioxide becomes incorporated into an organic molecule
reaction in which rubisco attaches oxygen instead of carbon dioxide to ribulose bisphosphate
ribulose bisphosphate carboxylase. carbon-fixing enzyme of the Calvin-Benson cycle
gaps that open between guard cells on plant surfaces
involving or occurring in the presence of oxygen
aerobic respiration
aerobic pathway that breaks down carbohydrates to produce ATP
occurring in the absence of oxygen
set of reactions in which glucose or another sugar is broken down to two pyruvate for a net yield of two ATP
photosynthetic autotroph
three-carbon end product of glycolysis
Krebs cycle
cyclic pathway that, along with acetyl-CoA formation, breaks down two pyruvate to carbon dioxide for a net yield of two ATP and many reduced coenzymes
alcoholic fermentation
anaerobic carbohydrate breakdown pathway that produces ATP and ethanol
an anaerobic pathway by which cells harvest energy from carbohydrates
lactate fermentation
anaerobic carbohydrate breakdown pathway that produces ATP and lactate
