For every six CO2 molecules incorporated into carbohydrate molecules, how many triose phosphates can be exported from the chloroplast?

The Calvin cycle, which occurs in the chloroplast, is responsible for converting carbon dioxide into carbohydrates. For every three CO2 molecules that enter the cycle, one glyceraldehyde 3-phosphate (G3P) molecule is produced. G3P is a triose phosphate, and it can be exported from the chloroplast and used to produce glucose and other carbohydrates.

So, if we want to know how many triose phosphates can be exported for every six CO2 molecules, we just need to double the amount produced for three CO2 molecules.

Therefore, for every six CO2 molecules incorporated into carbohydrate molecules, two triose phosphates can be exported from the chloroplast.
