Question

select the phase(s) of the calvin cycle during which atp is used. phase(s) answer bank carboxylation regeneration reduction

Explanation:

In the Calvin - cycle, ATP is used in the reduction phase to convert 3 - phosphoglycerate to glyceraldehyde - 3 - phosphate, and also in the regeneration phase to convert glyceraldehyde - 3 - phosphate back to ribulose - 1,5 - bisphosphate. Carboxylation phase uses only the enzyme RuBisCO and carbon dioxide, not ATP.

Answer:

regeneration, reduction
