How many carbon dioxide molecules must enter the Calvin-Benson cycle to produce one sugar phosphate?

Three CO2 molecules enters one Calvin cycle.

6 molecules of carbon dioxide .

There is one and two Oxygen MoleculesThe molecule can be represented as : O=C=O as each oxygen has 2 bonds with the single carbon atom.

Six. Technically speaking, three turns of the Calvin cycle produce one Glyceraldehyde-3-phosphate (G3P). Each turn of the Calvin Cycle uses 1 CO2. So three CO2 (3 cycles) for 1 G3P. Since 2 G3P are...
