Question

In one to three sentences, describe what happens during the carbon fixation stage of the Calvin cycle.

Answer 1

What did you include in your answer?

Carbon dioxide (CO2) combines with a five-carbon compound

3-phosphoglycerate (PGA) is formed.

Answer 2

In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively.
