What does atp add to the calvin-benson cycle? a) carbon atoms b) hydrogen atoms c) chemical energy d) electrons

The correct answer is option C) chemical energy.

Explanation:

In the Calvin cycle or Calvin-Benson cycle ATP adds chemical energy to convert three molecules of CO₂ to one molecule of the 3- carbon sugar. Later in the regeneration stage ATP is again required. In the Calvin-Benson cycle, nine ATPs are converted into nine ADPs, out of which six ATPs are used during the fixation stage and rest three in the regeneration stage.

the correct option is option d
