The process of carboxylation of RuBP (Ribulose-1,5-bisphosphate) by the enzyme Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is the first major step of the Calvin cycle in photosynthesis.

In this process, each molecule of RuBP is carboxylated to form two molecules of 3-phosphoglycerate (3-PGA). This reaction does not directly involve NADPH.

However, in the subsequent steps of the Calvin cycle, these 3-PGA molecules are reduced to glyceraldehyde-3-phosphate (G3P) in a process that requires NADPH. Specifically, each 3-PGA molecule requires 1 molecule of NADPH for its reduction.

So, for each RuBP molecule that is carboxylated, 2 molecules of NADPH are required (because each RuBP produces 2 molecules of 3-PGA).

Therefore, for 12 molecules of RuBP to be carboxylated, 12 * 2 = 24 molecules of NADPH would be required.
