Net primary productivity The rate of total energy acquisition by green plants during photosynthesis, minus the rate of energy loss through plant respiration. 

A close inspection of Fig. 1 will reveal that in the anaerobic breakdown of glucose to pyruvic acid a total of four energy-rich ( ) bonds are synthesized. However, of these four bonds, one bond is utilized in the primary phosphorylation step of glucose glucose-6-phosphate, and a second is consumed at the fructose-6-phosphate fructose diphosphate level. Hence a net synthesis of only two bonds is realized.
