Question

Which of the following is true if cells need R5P but not NADPH?A. G6P is converted to Ru5PB. Glycolysis provides GAP and F6P to make R5PC. R5P can not be made without co-generating NADPHD. R5P can not be made using the intermediates of glycolysis

Answer 1

Answer:

B. GLYCOLYSIS PROVIDES G3P AND F6P TO MAKE R5P

Explanation:

Ribose-5-phosphate is produced by the pentose phosphate pathway which is a process that works in line with glycolysis.

The need for NADPH and cell growth determines the production of ribose-6-phosphate in the cell.

Glucose-6- phosphate controls the flow of production from these two processes (pentose phosphate pathway and glycolysis)

During glycolysis, glycolytic intermediates can be used to produce R5P. This is so when the cells demands R5P than it desires NADPH

Glucose -6- Phosphate is converted to fructose-6-phosphate and glycealdehyde-3-phosphate during this process.

Two molecules of fructose-6-phosphate and a molecule of glyceraldehyde-3-phosphatr are then converted to three molecules of Ribose-5-phosphate by enzymes transketolase and transaldolase.
