16. If both NADPH and ribose-5-P are needed in the cells 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 + 6 H⁺
(C) Gluc-6-P + 2 NADP⁺ +2 H₂O → 2 NADPH + CO₂ + ribose-5-P +2 H⁺
(D) Gluc-6-P + 12 NADP⁺ +6 H₂O →12 NADPH +. 6 CO₂ + 12 H⁺ + Pi
(E) None of the above.
