plants capturing energy from the sun and converting it into chemical energy that will be stored in the sugars it will make.
organisms that can make their own food. "Self-feeder" or producers
"other feeders" or consumers
plant organelle where photosynthesis occurs)
Location of photosynthesis
leaves; specifically in chloroplasts
the pigment involved in photosynthesis.
where gases are exchanged
the fluid within the inner membrane of the chloroplasts
stacks of thylokoid
flattened close sacs that stack
Overall equation & Tracking the Atoms Through Photosynthesis
6CO2 + 12H2O (light and chorophyl) => C6H12O6 + 6H20 + 6O2
absorb different wavelengths of visible light
The most important of the two Chlorophyll; found in plants, green algae, and cynobacteria. The differentiating side group is CH3
found only in plants and green algae; differentiating side group is CHO
yellow-orange pigments that absorbs light in photosynthesis; embedded in the thylakoid membranes; yellow-orange vegetables have this (carrots)
focuses energy from the light into the reaction center; very spec center
where the photon is going to be focused and where the electrons will be excited; contains two chlorophyll A molecules; the ultimate pigment responsible
Primary Electron acceptor
accepts electron passed from the reaction center, after electrons has been excited and moved to the outer energy level; holds the electron (redox reaction (oxidation and reduction reaction))
occurs when something gains an electron as in the case with the Primary Electron Acceptor.
aka p680; absorbs light less red, to the left; where initial excitation of electrons occur
aka P700; absorbs wavelengths of light in the red area; where 2nd excitation of electrons occur
A "pool" of molecules within the thylakoid membranes; links PSII to PSI; also aids the Cytochrome complex in the pumping of H+ from the stroma to the lumen
next step after H+ Pumping by Plastoquinones; and exists between PSII and PSI;
shuttles electrons from the Cytochrome complex to the PSI
an iron sulfur protein that acts as another mobile electron carrier of the pathway; then transfers to the NADP+ reductase
Cyclic Electron Flow
only uses PSI; Excited electrons cycle back to PSI; ATP is produced, but not NAPDH; Electron are sent back to the Ferrodoxin then to the Cytochrome complex.
Destination of Oxygen -
Out of the cell
Destination of ATP -
in the liquid stroma
Destination of NADPH
to light independent reactions
where the sugars are actually made
3 Co2 (atmosphere) react w 3 ribulose bisphosphates (needed for making sugars)(RuBP) forming 3 unstable 6C compounds.
catalyzes the reaction of Carbon Fixation; the most abundant enzyme/protein on earth
Location of the Calvin Cycle
the unstable compound broken down during Carbon fixation
