Photosynthesis Flashcards
This is a process where plants convert radiant energy from the sun into chemical energy in the form of glucose (sugar)
Photosynthesis
Where does chlorophyll reside in the cell?
Thylakoid Membrane
O2 is formed by what during photosynthesis?
H2O
What type of reaction is photosynthesis?
Redox Reaction
During photosynthesis, electrons increase in potential energy therefore making it what type of reaction?
Endergonic
What form of energy is light?
Electromagnetic Radiation
What is the range of visible light (in nm)?
380-750nm
These are discrete particles with a fixed amount of energy but have no mass
Photons
What is pigment?
Substance that absorbs visible light
Why does chlorophyll appear to be green?
Chlorophyll doesn’t absorb the wavelengths in the green part of the color spectrum
What happens in a light reaction?
Light energy is converted into chemical energy
What happens as a result of a light reaction? (4 parts)
- H2O is split to provide e(-) and H(+)
- NADP(+) is reduced to NADPH
- ATP is produced
- O2 is given off
What:
- fixes carbon from CO2 into organic molecules
- reduces fixed carbon into sugar using the NADPH and ATP from light reactions
Calvin Cycle
Photosystems, which capture light, are located where in the cell?
Thylakoid Membrane
These contain pigment molecules which absorb light and transfer energy to reaction-center complex
Antenna Complexes
