The following statements are related to pentose phosphate pathway.

a) The first and third steps are oxidations with large, negative standard free-energy changes and are essentially irreversible in the cell

c) All the enzymes of the reversible reaction of the pentose phosphate pathway are located in the cytosol

d) The NADPH is used for biosynthetic reactions such as lipid synthesis and nitrogen assimilation in the cytosol
