what transformations take place in photosynthesis?how does glucose help in the formation of ATP from ADP?

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, whichcellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!

We can write the overall reaction of this process as:

6H₂O + 6CO₂ ----------> C₆H₁₂O₆+ 6O₂

Most of us don''t speak chemicalese, so the above chemical equation translates as:

six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen
