How many molecules of ATP and NADPH are needed to fix a molecule of CO 2 in C 3 plants? Where does this process occur?

In C3 plants, fixing a molecule of CO 2 requires 3 ATP and 2 NADPH molecules. Six Calvin cycle turns are needed to fix six carbon atoms from CO2. In the reduction step, 12 ATP molecules and 12 NADPH molecules are required, and in the regeneration step, 6 ATP molecules are needed. A total of 18 ATP molecules and 12 NADPH is required for fixation of 6 molecules of CO 2 . The process occurs in mesophyll cells to bundle sheath cells.
