The net reaction of the transketolase and transaldolase steps in the pentose phosphate pathway involves the conversion of three 5-carbon sugars (pentoses) into two 6-carbon sugars (hexoses) and one 3-carbon sugar (triose), which is accurately represented by option A: $3 \mathrm { C } _ { 5 } \rightleftharpoons 2 \mathrm { C } _ { 6 } + \mathrm { C } _ { 3 }$.
