1 ) The precursor molecules that are generated in the Pentose Phosphate path are 1 , Glucose - 6 - phosphate 2 , NADPH
Glycolysis forms the backbone of central carbon metabolism. Pentose phosphate path used to synthesize the nucleotides for DNA replication and RNA production . Pentose phosphate path provides an alternate pathway to glycolysis for the metabolism of glucose , and the percentage of glucose is metabolized through pentose phosphate pathway .
Both DNA and RNA are polymers of nucleotides, which consists of a five carbon sugar , a nitrogen containing base and a phosphate group, of these five carbon sugars which are also called as pentoses , are mainly synthesized through the pentose phosphate path .Therefore this pathway is essentially important for nucleotide synthesis , and also produces NADPH which is not only is involved in the regulation of reactive oxygen speciesthrough the maintenance of reduced glutathione pool, but also serves as cofactor in biosynthesis of several essential macro molecules, such as lipids and aminoacids.
Glucose - 6 - phosphate is plays an important role in both the synthesis of nucleotides .
2 ) Cyanobacteria are organisms that have single photosystem , the electron transport may be regulated indirectly by controlling the transfer of excitation energy from the light harvesting complexes , or it may be more directly regulated by controlling localization , and interactions of photosynthetic and respiratory electron transport complexes . Cyclic electron transport is particularly important for controlling the redox balance of the cell .
The thylakoid membranes of cyanobacteria are a complex intracytoplasmic membrane system that houses the photosynthetic electron transport chain , and also most of the respiratory electron transport complexes .
