oxygen and water
sugar and water
water and carbon dioxide
sugar and oxygen
oxygen and water
sugar and water
water and carbon dioxide
.... is the final electron acceptor in photosystem I
Which best describes light-independent reactions?
They are the first stage of photosynthesis.
They utilize the energy stored in ATP and NADPH.
They use carbon dioxide to synthesize proteins.
They create energy-rich ATP and NADPH.
They utilize the energy stored in ATP and NADPH.
Organism that performs the most photosynthesis on earth:
algae
trees
grass
cyanobacteria
Special organelles in phototrophic cells that are the place of photosynthesis:
Chloroplasts
Pigment in chloroplasts that absorbs sunlight and reflects colors other than green
chlorophyll
RuBP
caretonoids
What does the equation [ Sunlight +6H20 + 6CO2--&rt; C6H1206 +6O2 ] represent?
cell respiration
human respiration
photosynthesis
solar energy
Energy is never created or destroyed, it only is transfered from one thing to another.
false
true
Light-harvesting complexes, excited by photons of light, are made of
pigment and sugars
proteins and sugars
proteins and water
proteins, cofactors, and pigment
proteins, cofactors, and pigment
When electrons are passed through an electron transport chain, released energy
splits water into hydrogen and oxygen.
is transformed into a hydrogen ion gradient to drive ATP synthesis.
is lost as heat.
fuses carbon dioxide molecules into a sugar.
is transformed into a hydrogen ion gradient to drive ATP synthesis.
Why do plants appear green?
They absorb green light.
They reflect green light.
They absorb electrons by green pigments when exposed to sunlight.
They excite electrons which emit green light in the visible spectrum.
They reflect green light.
When a photon of light energy reaches a reaction center chlorophyll molecule, what becomes excited?
a molecule of water vapor
a carbon dioxide molecule
an electron
a carbon monoxide molecule
Light Independent Reaction of Photosynthesis is called
Calvin Cycle
