Unit 3 List 3 Cell Energy Flashcards
Autotroph
an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
Light Dependent Reactions
convert light energy into chemical energy.
Chlorophyll
the natural compound present in green plants that gives them their color
Photosynthesis
the process by which green plants and certain other organisms transform light energy into chemical energy.
Calvin cycle
a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose.
Electron Transport Chain
a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP
NADPH
Nicotinamide adenine dinucleotide phosphate
Pigment
a substance that gives color to other materials.
Granum
Stomata
a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere.
Carbon Fixation
the process by which inorganic carbon is added to an organic molecule.
Heterotrophs
an organism that eats other plants or animals for energy and nutrients.
Thylakoids
tiny compartments found inside of chloroplasts
Carotenoids
tetraterpene pigments, which exhibit yellow, orange, red and purple colors.
Stroma
The cells and tissues that support and give structure to organs, glands, or other tissues in the body.
