In which cellular compartment does the pentose phosphate pathway (PPP) primarily occur?

✅Explanation:
The pentose phosphate pathway (PPP) primarily occurs in the cytosol of the cell. This pathway is involved in the production of NADPH and ribose-5-phosphate, which are essential for anabolic reactions, including the synthesis of nucleotides and fatty acids.
The PPP also helps in the metabolism of carbohydrates by providing an alternative route to glycolysis for glucose-6-phosphate. The reactions of the PPP do not occur in the mitochondria or peroxisomes, but are confined to the cytosolic compartment of the cell.
