|
adenosine triphosphate (ATP)
|
compound used by cells to store and release energy
|
|
|
heterotroph
|
organisms that obtain food by consuming other living things
|
|
|
autroph
|
organsims that make their own food
|
|
|
photosynthesis
|
process where autotrophs use the energy of sunlight to produce high energy carbohydrates that can be used as food
|
|
|
pigment
|
light absorbing molecules
|
|
|
chlorophyll
|
principle pigment of plants and other photosynthetic organsims
|
|
|
thylakoid
|
abundance of sac like photosynthetic membranes
|
|
|
stroma
|
fluid portion if the cholorphyll outside the thylakoid
|
|
|
NADP+
|
carrier molecule that transfers high energy electrons from chlorophyll to other molecules
|
|
|
light dependent reactions
|
require direct involvment of light and light-absorbing pigments
|
|
|
light independent reactions
|
set of reactions in photosynthesis that does not require light
|
|
|
photosystem
|
thylakoids containing clusters of chlorophyll and protiens
|
|
|
electron transport chain
|
a series of electron carrier protiens that shuttle high-energy electrons during ATP-generating reactions
|
|
|
ATP synthase
|
protien that spans the membrane and allows H+ ions to pass through it
|
|
|
calvin cycle
|
light independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar
|
|
|
what is the role of ATP in the cell?
|
easily release and store energy by brealing and re-forming bonds between its phosphate groups
|
|
|
what is the ultimate source of energy for plants
|
sunlight
|
|
|
why are pigments such as chlorophyll needed for photosynthesis?
|
photosynthetic organisms capture energy from sunlight with them
|
|
|
what are the reactants and products of photosynthesis?
|
photosynthesis used the energy of sunlight to convert water and carbon dioxide(reactants) into high-energy sugars and oxygen(products)
|
|
|
what are the three primary factors that affect the rate of photosynthesis?
|
temperature, light, and water
|
|
|
what happens during the process of photosynthesis?
|
plants convert the energy of sunlight into chemical energy and sunlight into chemical energy stored in the bonds of carbohydrates.
