Part A Where is the most energy used in the Calvin cycle? View Available Hint(s) in the fixation of $$CO_2$$ to RuBP in the linkage of two G3P molecules together to form glucose in the regeneration of RuBP in the conversion of PGA to G3P in the rearrangement of the six-carbon molecule made from RuBP and $$CO_2$$ into the three-carbon molecules of PGA Submit Provide Feedback

Step 1
The Calvin cycle consists of three main phases: carbon fixation, reduction, and regeneration of RuBP. Energy in the Calvin cycle is supplied in the form of ATP and NADPH. Show more…
