If a plant cell undergoes 6 loops of the Calvin Cycle, using 6 molecules of CO2, how many ATP will be needed to generate all of the RuBP that was used in the fixation stage?
In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO2. These six turns require energy input from 12 ATP molecules and 12 NADPH molecules in the reduction step and 6 ATP molecules in the regeneration step.
