Question

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

Answer 1

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 NADPH+

Answer 2

G3P is converted into RuBP. The enzyme rubisco speeds up the reaction.
