If NADPH Is Needed for Biosynthetic Reactions but Ribose-5-P Is

If NADPH is needed for biosynthetic reactions but ribose-5-P is not needed, which of the following best represents the net reaction of the pentose phosphate pathway?

A) 4 Fruc-6-P + 2 glyceraldehyde-3-P → 6 ribose-5-P
B) 3 Gluc-6-P + 6 NADP⁺ → 6 NADPH + 3 CO₂ + 2 Fruc-6-P + 1 glyceraldehyde-3-P
C) Gluc-6-P + 2 NADP⁺ → 2 NADPH + CO₂ + ribose-5-P
D) both b and c will occur
E) None of the above
