There are 3 parts to this question (AC) 5. Concerning the pentose phosphate pathway. A In the nonoxidative phase of the pentose phosphate pathway, from where does the xylulose-5-phosphate come? B. At the end of the nonoxidative portion of the pentose phosphate pathway the result is 2 molecules of fructose-6-phosphate and 1 molecule of glyceraldehyde-3-phosphate Toget this, how many times did the oxidative phase have to run lie, how many glucose-6-phosphate molecules were used? C. How many total NADPH will...
