Photosynthesis Campbell Ch. 10

Front

absorption spectrum

Back

range of wavelengths of electromagnetic radiation absorbed by a given substance

Front

Calvin cycle

Back

light-independent reactions of photosynthesis that convert carbon dioxide from the atmosphere into carbohydrates using the energy and reducing power of ATP and NADPH

Front

carbon fixation

Back

process of converting inorganic CO2 gas into organic compounds

Front

carotenoid

Back

Front

chemoautotroph

Back

organism that can build organic molecules using energy derived from inorganic chemicals instead of sunlight

Front

chemoheterotroph

Back

organism that must take in organic molecules for both energy and carbon

Front

chlorophyll a

Back

form of chlorophyll that absorbs violet-blue and red light and consequently has a bluish-green color; the only pigment molecule that performs the photochemistry by getting excited and losing an electron to the electron transport chain

Front

chlorophyll b

Back

accessory pigment that absorbs blue and red-orange light and consequently has a yellowish-green tint

Front

chloroplast

Back

organelle in which photosynthesis takes place

Front

electron transport chain

Back

group of proteins between PSII and PSI that pass energized electrons and use the energy released by the electrons to move hydrogen ions against their concentration gradient into the thylakoid lumen
