Openstax Ch. 8 Photosynthesis Vocabulary Test

Range of wavelengths of electromagnetic radiation absorbed by a given substance

pigment molecule that directly absorbs light and transfers the energy absorbed to other pigment molecules

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

process of converting inorganic CO2 gas into organic compounds

photosynthetic pigment that functions to dispose of excess energy

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

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

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

organelle in which photosynthesis takes place

group of reversibly oxidizable and reducible proteins that forms part of the

range of all possible frequencies of radiation

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

stack of thylakoids located inside a chloroplast

organism that consumes organic substances or other organisms for food

complex that passes energy from sunlight to the reaction center in each photosystem; it consists of multiple antenna proteins that contain a mixture of 300-400 chlorophyll a and b molecules as well as other pigments like carotenoids
