Photosynthesis Lab Flashcards
what is photosynthesis?
process used by plants to harness energy and turn into chemical energy
photosynthesis equation
6CO2 + 12H2O + energy –> C6H12O6
What are the two stages of photosynthesis?
light depended reaction
calvin cycle
Where does photosynthesis occur?
in the chloroplast
Where does the Light Dependent Reaction occur?
thylakoid disk inner membrane
What are the three parts of the Light Dependent Reaction?
photosystem 2
electron tranpost system
and photosystem 1
Antenna Complex
it is multiple chlorophyll molecules capturing photonic energy which is sent to the reaction center
Reaction Center
gather that photonic energy given from the antenna complex and elevates/excites the electron into the electron transport system
What does the Electron Transport System generate in the Light Dependent Reaction?
through a proton gradient(chemiosmosis), a hydrogen ion is released into the thylakoid space creating an ATP molecule. that H+ ion released binds with H2O which is used by the reaction center in photosystem 2 to keep the reaction going.
In photosystem 2, the reaction center is excited by what?
the electron transfered from photosystem 1 and the photonic energy created by the antenna complex
Once the electrons are excited in photosystem 2 what molecules accept those electrons?
NADP reductase accepts those electrons which turn into NADPH (high energy electrons)
What are the end products of the Light Dependent Reaction?
ATP and NADPH
What type of plants undergo the calvin cycle normally?
C3 plants
What is the first phase of the calvin cycle?
carbon fixation
What does the 3 CO2 bind to at the beginning of the calvin cycle?
Rubisco a 5 carbon molecule
