NADPH is produced by -
Glycolysis
Citric acid cycle
Hexose monophosphate shunt
Glycogenesis
Ans. is 'c' i.e., Hexose monophosphate shunt o HMP shunt is particularly important for two purposesi) Synthesis of ribose for nucleotide and nucleic acid formation.ii) Formation of NADPH which plays important role in several other biological processes, e.g. synthesis of fatty acids, cholesterol, steroid hormones and neurotransmitters.
