There are many enzymes working in photosynthetic reactions - such as the enzyme in photolysis. These enzymes will stop working properly at high or low temperatures and therefore, so will the light-dependent and light-independent reactions.
The hydrogen converts to which is then used in the light-independent reactions. Oxygen out of the plant as a waste product of photosynthesis and ATP is synthesised from and inorganic phosphate. This all happens in the grana of chloroplasts.

An even closer form of symbiosis may explain the origin of chloroplasts. Chloroplasts have many similarities with including a circular , prokaryotic-type , and similar proteins in the photosynthetic reaction center. The suggests that photosynthetic bacteria were acquired (by ) by early cells to form the first cells. Therefore, chloroplasts may be photosynthetic bacteria that adapted to life inside plant cells. Like , chloroplasts still possess their own DNA, separate from the of their plant host cells and the genes in this chloroplast DNA resemble those in . DNA in chloroplasts codes for proteins such as photosynthetic reaction centers. The proposes that this Co-location is required for Redox Regulation.
Light and Dark Reaction of photosynthesis
chemically fix carbon dioxide in the cells of the by adding it to the three-carbon molecule , a reaction catalyzed by an enzyme called and which creates the four-carbon organic acid, . Oxaloacetic acid or synthesized by this process is then translocated to specialized cells where the enzyme, rubisco, and other Calvin cycle enzymes are located, and where CO2 released by of the four-carbon acids is then fixed by rubisco activity to the three-carbon sugar . The physical separation of rubisco from the oxygen-generating light reactions reduces photorespiration and increases CO2 fixation and thus photosynthetic capacity of the leaf. C4 plants can produce more sugar than C3 plants in conditions of high light and temperature. Many important crop plants are C4 plants including maize, sorghum, sugarcane, and millet. Plants lacking PEP-carboxylase are called because the primary carboxylation reaction, catalyzed by rubisco, produces the three-carbon sugar 3-phosphoglyceric acids directly in the Calvin-Benson Cycle.
