Cell Energy Vocab Flashcards
An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Autotroph
Uses light energy to make two molecules needed for the next stage of photosynthesis.
Light Reactions
The natural compound present in green plants that gives them their color.
Chlorophyll
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Photosynthesis
Used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Calvin cycle
A series of four protein complexes that couple redox reactions
Electron Transport Chain
Represents one of the most important electron donors found in all living organisms.
NADPH
A coin-shaped stack of thylakoids, which are the membrane-like structures found inside the chloroplasts of plant cells.
Granum
The natural coloring matter of animal or plant tissue.
Pigment
The conversion of atmospheric carbon dioxide into organic molecules by autotrophic organisms.
Carbon Fixation
A pore or aperture surrounded by two guard cells that allow gas exchange.
Stomata
An organism that eats other plants or animals for energy and nutrients.
Heterotrophs
Internal photosynthetic membrane systems of chloroplasts.
Thylakoids
Pigments found in plants and microorganisms, but not synthesized in animals.
Carotenoids
A gel-like material in the mitochondrion, or organelle that performs the process of aerobic respiration, that contains ribosomes resembling those of bacteria.
Mitochondrial matrix
