Solution
Verified by Toppr

Pentose phosphate pathway is also called as phosphogluconate pathway or Hexose Monophosphate Shunt (HMP Shunt). It occurs in most organisms in cytoplasm. It results in generation of NADPH, ribose-5-phosphate (R5P) and erythrose 4-phosphate (E4P). R5P is precursor for the synthesis of nucleotides. E4P is involved in the synthesis of aromatic amino acids.
Thus, the correct answer is option B.
