Calvin Cycle Diagram Labelled. The calvin cycle reactions figure 2 can be organized into three basic stages. Diagram of the calvin cycle illustrating how the fixation of three carbon dioxide molecules allows one net g3p molecule to be produced that is allows one g3p molecule to leave the cycle.
These plants are very efficient in hot dry climates and make a lot of energy. Here is a general diagram of the cycle. Carbon is an essential component that makes up the complex molecules of various organisms humans included.
The pga molecule enters the calvin cycle to make carbohydrates but one co 2 molecule released in mitochondria during photorespiration has to be re fixed.
A car boxylation during which atmospheric co 2 combines with 5 c acceptor molecule ribulose 1 5 bisphosphate rubp and converts it into 3 phosphoglyceric acid 3 pga. In the stroma in addition to co 2 two other chemicals are present to initiate the calvin cycle. In the first stage chemical reactions use energy from light to produce atp and nadph. The presence of carbon in living organisms distinguishes them from inorganic elements whose compounds lack the said element.
