Chlorophyll and photosynthesis
Pigments in the leaves of green plants and algae
The fluorescence of chlorophyll
Fluorescence: The excitement of an electron to a high energy level by the action of light energy. Followed by the release of that energy as light again as the electron falls back to its former low energy level.
Something must be happening in the chloroplast to capture these electrons and use their energy.
Free electrons can lead to OXIDATION AND REDUCTION reactions.
When compounds are oxidised energy is released.
If this release of energy is COUPLED to biological reactions then WORK can be done.
Similarly when compounds are reduced, energy has to be put into the system.
In photosynthesis the source of electrons for reducing
CO2 CH2O is water and the source of energy is light.
