The reversible interconversion reactions of the pentose phosphate pathway can operate either to convert pentoses to hexoses, when operating in an oxidative mode to generate NADPH , or to convert hexoses to pentoses, when operating in a non‑oxidative mode to generate pentoses for nucleic acid synthesis. Two key enzymes in these interconversion reactions are transaldolase and transketolase. Identify the products formed from the seven‑carbon sugar sedoheptulose‑7‑phosphate and glyceraldehyde‑3‑phosphate with each of these enzymes.

Respuesta :

Answer:

The products are fructose-6- phosphate and erythrose- 4- phosphate

Explanation:

Transketolase and transaldolase are the two important enzymes of  nox oxidative phase of Pentose phosphate pathway.

   Transketolase helps xylulose-5- phosphate and Ribose -5-phosphate to interact thus resulting in the formation of sedohptulose-7-phosphate and glyceraldehyde-3-phosphate.

 The soformed sedoheptulose-7-phosphate and glyceraldehyde-3-phosphate interact with each other in presence of transaldolase enzyme to generate fructose -6-phosphate and erythrose-4-phosphate.
