Energy gain from PGA to PGAL in Calvin Cycle.

Molecules can be studied in terms of the amount of energy in their chemical bonds. Note that in the Calvin-Benson cycle there is a large increase in the amount of chemical energy as the cycle goes from the three carbon molecule PGA to the molecule G3P. Most of this increase is due to the redox step 5 In which hydrogens and electrons are transfered from the NADPH to the 3 carbon molecules.
