Describe the interconversions between the triose-, pentose-, and hexose-phosphate metabolic pools in the plant cell.
a. Triose phosphate is converted to pentose phosphate by transketolase; pentose phosphate is converted to hexose phosphate by phosphoglucoisomerase.
b. Triose phosphate is converted to hexose phosphate by phosphoglucoisomerase; hexose phosphate is converted to pentose phosphate by transketolase.
c. Hexose phosphate is converted to pentose phosphate by transketolase; pentose phosphate is converted to triose phosphate by phosphoglucoisomerase.
d. Pentose phosphate is converted to triose phosphate by phosphoglucoisomerase; triose phosphate is converted to hexose phosphate by transketolase.
