Unit 4 List 1 Cell Energy Flashcards
(15 cards)
Autotroph
Autotrophs are producers who prepare their own food. Heterotrophs are consumers who depend on other sources for their food.
Light Dependent Reactions
use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.
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
light-independent reactions in photosynthesis that take place in three key steps.
Electron Transport Chain
a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation.
NADPH
Nicotinamide adenine dinucleotide phosphate
Pigment
a substance that gives color to other materials.
Granum
a stack of coin-shaped thylakoids in the chloroplasts of plant cells.
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 from the atmosphere is assimilated into living organisms and converted into organic compounds
Heterotrophs
Autotrophs are producers who prepare their own food. Heterotrophs are consumers who depend on other sources for their food.
Thylakoids
pouch-like sacs that are bound to a membrane in the chloroplasts of a plant cell.
Carotenoids
pigments in plants, algae, and photosynthetic bacteria.
Stroma
The cells and tissues that support and give structure to organs, glands, or other tissues in the body.
