For compounds involved in more than one reaction the small numbers against the arrow indicate the number of molecules proceeding along each branch. Similarly for compounds derived from more than one reaction the number of molecules derived from each route are indicated by a small number against the arrow.

The net overall reaction is:

6 CO2 + 12 NADPH + 18 ATP + 11 H2O = D-glucose 6-phosphate + 12 NADP+ + 18 ADP + 17 phosphate
