Mastery Test Chapter 8 Flashcards
Photosynthesis
Process where plants get energy from sunligh
Adenosine triphosphate
ATD
Pigment
Color substance for plants
Chlorophyll
a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
Thylakoid
each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
Stroma
The spongy, colorless matrix of a cell that functionally supports the cell.
Photo system
biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis
Electron transport chain
Electrons that transfer into reactions
ATP synthase
An enzyme that catalyzes the formation of ATP from the phosphorylation of ADP
Calvin cycle
a metabolic pathway found in the stroma of the chloroplast in which carbon enters in the form of CO2 and leaves in the form of sugar.
Heterotroph
Organism that eats both plants and animals
NADP
cofactor used in anabolic reactions
Light-dependent reactions
reactions that depend on light
Light-independent reactions
reactions that don’t depend on light
Autotroph
Producer
