Chemical formula for photosynthesis

Allphotosynthetic organisms--with the exception of a minor group ofbacteria, the halobacteria--contain the light-absorbing pigmentchlorophyll, which plays a key role in the transfer of energy fromlight to chemical compounds.Photosynthesis is the fundamental process that maintains life onEarth.

Photosynthesis converts light energy into the chemical energy of sugars and other organic compounds

In a broad chemical sense, the opposite of photosynthesis isrespiration. Most of life on this planet (all except in the deepsea vents) depends on the reciprocal photosynthesis-drivenproduction of carbon containing compounds by a series of reducing(adding electrons) chemical reactions carried out by plants andthen the opposite process of oxidative (removing electrons)chemical reactions by animals (and plants, which are capable ofboth photosynthesis and respiration) in which these carboncompounds are broken down to carbon dioxide and water.

Photoaututrophs utilize sunlight for energy and CO2 for theircarbon source by this process of PHOTOSYNTHESIS whereby sunlightis absorbed by a complex compound known as chlorophyll andconverted to energy which drives a series of chemical reactionsthat ultimately removes hydrogen from water or other compoundsand then combines the hydrogen with carbon dioxide in a way thatproduces sugars.


The conversion of usable sunlight energy into chemical energy ..

Human and animal life on earth completely depend upon the physical process of photosynthesis. If the physical photosynthetic process had never originated, this planet would be as barren as earth's moon. Primarily, there would be no oxygen in our atmosphere and nothing for lungs or gills to breathe, all would be in suffocation. As human and animal respiration inhales oxygen and exhales carbon dioxide, green plants, by means of photosynthesis, take in carbon dioxide and emit oxygen through two cycles of light and dark. Light waves consist of quanta of light (photons) primarily emitted by the sun; these massless photons traveling at high velocity interact with Chloroplast organelles of green plants, combining with water, carbon dioxide, and minerals to produce oxygen. Massless, high velocity photons are an energy source and as such, within the chemical processing plant, produce electric power. Green plants produce three times the amount of electric power per year than all human habitats produce globally per year.

The Chemical Equation of Photosynthesis

In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose bisphosphate (RuBP). Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates such as glucose.The general equation for photosynthesis is therefore:Photosynthetic membranes and organellesIn plants and algae, photosynthesis takes place in organelles called chloroplasts.
