| photoautotroph |
Phototrophs or photoautotrophs are photosynthetic algae, fungi, bacteria and cyanobacteria which build up carbon dioxide and water into organic cell materials using energy from sunlight. One product of this process is starch, which is a storage or reserve form of carbon, which can be used when light conditions are too poor to satisfy the immediate needs of the organism. ...

| phosphagen |
The phosphagens are energy storage compounds, also known as high energy phosphate compounds, are chiefly found in muscular tissue in animals. They allow a high energy phosphate pool to be maintained in a concentration range which, if it all were ATP, would create problems due to the ATP consuming reactions in these tissues. Muscle tissues will have sudden demands for lots of energy. ...

| photopsin |
Photopsins are the photoreceptor pigments found in the cone cells of the retina that are the basis of color vision. Photopsins are very close analogs of the visual purple rhodopsin that is used in dark vision. Photopsins consist of a protein called opsin and a bound chromophore, the retinal. Different opsins differ in a few amino acids and absorb light at different wavelengths as retinal-bound pigments. Opsins are G protein-coupled receptors. ...
