The Calvin cycle accounts for 90% of biological carbon fixation.  Consuming ATP and NADPH, the Calvin cycle in plants accounts for the preponderance of carbon fixation on land. In algae and cyanobacteria, it accounts for the preponderance of carbon fixation in the oceans. The Calvin cycle converts carbon dioxide into sugar, as triose phosphate (TP), which is glyceraldehyde 3-phosphate (GAP) together with dihydroxyacetone phosphate (DHAP):
:3 CO  +  12 e  +  12 H  +  P   →   TP   +   4 HO
An alternative perspective accounts for NADPH (source of e) and ATP:
:3 CO  +  6 NADPH  +  6 H  +  9 ATP  +  5 HO   →   TP  +  6 NADP  +  9 ADP  +  8 P
The formula for inorganic phosphate (P) is HOPO + 2H. Formulas for triose and TP are CHO-CHOH and CHO-CHOPO + 2H
