| photophosphorylation |
The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. Light absorbed by chlorophyll or other photosynthetic pigments is used to drive a transfer of electrons and hydrogen from water (or some other donor molecule) to an acceptor called NADP+, reducing it to the form of NADPH by adding a pair of electrons and a single proton (hydrogen nucleus). ...

| phospho- |
Phosphorus, (from the Greek language Phosphoros meaning "light bearing"), is the chemical element in the periodic table that has the symbol P and atomic number 15. A multivalent, nonmetal of the nitrogen group, phosphorus is commonly found in inorganic phosphate rocks and in all living cells. Due to its high reactivity, it is never found as a free element in nature. ...

| photosensitivity |
Photosensitivity is the amount to which an object reacts upon receiving photons of light. Devices that are photosensitive include the human retina and photographic film. Film is photosensitive because it has a chemical reaction when struck by light. The same process is used in the electronic device known as a photocathode, which is a surface that emits electrons when struck by light. ...
