Question

The diagram represents part of a plant cell. Identify the name of the location in the plant cell where carbon fixation occurs.

Answer 1

The Process Of Photosynthesis: Carbon FixationAnd Reduction

The assimilation of carbon into organic compounds is the result of a complex series of enzymatically regulated chemical reactions—the dark reactions. This term is something of a misnomer, for these reactions can take place in either light or darkness. Furthermore, some of the enzymes involved in the so-called dark reactions become inactive in prolonged darkness; however, they are activated when the leaves that contain them are exposed to light.



C3 carbon fixation pathwayPathway of carbon dioxide fixation and reduction in photosynthesis, the reductive pentose phosphate cycle. The diagram represents one complete turn of the cycle, with the net production of one molecule of Gal3P. The nine molecules of ATP and six molecules of NADPH come from the light reactions.
