Define anabolism.

Find out where transketolase and epimerase reactions occur among the following:

i) $\mathrm{G}-3-\mathrm{P}+\mathrm{DHAP}⟶$ Fructose $-1-6-$ bisphosphate

ii) Sedoheptulose- $7-$ Phosphate $+\mathrm{G}-3-\mathrm{P}⟶$ Xylulose $-5-\mathrm{P}+$ Ribose $-5-$ Phosphate

iii) Ribose $-5-$ Phosphate $⟶$Ribulose $-5-$ Phosphate

iv) Xylulose $-5 -$Phosphate $⟶$ Ribulose$-5 -$ Phosphate

v) Fructose $- 6 -$Phosphate $+\mathrm{G}-3-\mathrm{P}⟶$ Xylulose$- 5 -$Phosphate $+$ Erythrose $-4-$Phosphate

The correct combination is
