Summarize the ways in which plants can be converted into energy.
Photosynthesis is a physiochemical process by which photosynthetic organisms convert light energy into chemical energy in the form of reducing power as NADPH and ATP, and use these chemicals to drive carbon dioxide fixation.
The net process of photosynthesis is described by the following equation:
6CO2+ 6H2O + Light Energy = C6H12O6 6O2
This equations simply state that carbon dioxide from the air and water combine in the presence of sunlight to form sugars; oxygen is released as a byproduct of this reaction.
Photosynthesis is a two-stage process: one is light dependent, which occur direct energy of light to make NADPH and ATP that are used in the dark reaction, a process of formation of ATP and inorganic phosphate by utilizing energy is called photophosphorylation and another is light independent, in which the products of the light reaction, ATP and NADPH, are used to make glyceraldehyde 3-phosphate from reduction of carbon dioxide.
While the above reaction are proceeding CO2 is diffusing into the chloroplast. In the presence of the enzyme Rubisco, one molecule of CO2 is combined with one molecule of RuBP and the first product of this reaction is two molecules of phosphogyceric acid (PGA). The PGA then participates in a cycle of reactions that results in the production of the sugars and in the regeneration of RuBP. The RuBP is then available to accept the another molecule of CO2 and to make more PGA.
