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.
