Light-independant reactions
- The Calvin Cycle; carbon dioxide fixation involves a five-carbon coumpound called ribulose
bisphosphate (RuBP) and an enzyme called ribulose bisphosphate caboxylase (ribisco). With
the catalytic help of rubisco, RuBP combines with CO2 to form an unstable six-carbon
compound which splits immediately into two molecules of a three-carbon compound, glycerate
bisphosphate (GP). GP is then reduced to a triose phosphate called glyceraldehyde
3-phosphate (GALP). This reaction requires hydrogen and energy from ATP; both are supplied
by the light-dependant reactions. About one-sixth of the total GALP is then used to make
glucose. This can be converted into other carbohydrates. The remaining five-sixths is
converted back to RuBP. The regeneration of RuBP requires phosphate from ATP
