In the Calvin cycle, the three-carbon molecule that will be immediately formed after carbon dioxide fixation occurs is

A) PS I.
B) glucose.
C) 3PG.
D) G3P.
E) RuBP.

Carbon Dioxide Fixation

Process by which carbon dioxide gas is attached to an organic compound; in photosynthesis, this occurs in the Calvin cycle reactions.

Calvin Cycle

A series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms, playing a crucial role in converting carbon dioxide and other compounds into glucose.

3PG

3-phosphoglycerate, an intermediate in the glycolytic pathway and the Calvin cycle, crucial for the synthesis of glucose and other carbohydrates.
