Reducing Power —the Synthesis and Utilization of Pyridine Nucleotides

Reducing Power—the Synthesis and Utilization of Pyridine Nucleotides 

Reduced pyridine nucleotides (NADH, NADPH) are essential coenzymes for a number of key metabolic pathways and therefore they are likely to play an important role in the germinating embryo, developing seedling and storage 

The oxidized pyridine nucleotide NADP is the coenzyme of glucose-6-phos-phate dehydrogenase (G6Pdh) and is a key link between the glycolysis pathway and the pentose phosphate pathway. The former requires a supply of NAD for one of its intermediate steps, as outlined below  

When NADP is in limited supply glycolysis proceeds at the expense of the pentose phosphate pathway, whereas in conditions of limiting NAD the reverse will be the case. Consequently, the 

On the basis of fragmentary evidence from work on cotyledons of pea and Vigna sesquipedalis [21, 143] the following sequence of events occurs during and after imbibition
