The complete conversion of a molecule glucose to six molecules of carbon dioxide

Question

The complete conversion of a molecule glucose to six molecules of carbon dioxide via glycolysis and the Krebs cycle requires 19 reactions. Put the reactions that are given below in the proper order, beginning with the phosphorylation of glucose to form glucose-6-phosphate and ending with the oxidation of malate to form oxaloacetic acid.

1) 1,3-bisphosphoglycerate + ADP --> 3-phosphoglycerate + ATP
2) fumarate + H2O --> malate
3) isocitrate + NAD+ --> alpha-ketoglutarate + NADH + H+ + CO2
4) phosphoenol pyruvate + ADP --> pyruvate + ATP
5) Succinyl-CoA + GDP + Pi --> succinate + GTP + CoASH
6) glyceraldehyde 3-phosphate + NAD+ + Pi --> 1,3-bisphosphoglycerate + NADH + H+

Thank you for the help!

Explanation / Answer

1.Here first is Glucose + ATP---------------> Glucose 6 Phosphate +ADP +H+

Glyceraldehyde 3 P +NAD+Pi ---->1,3bisphhosphoglycerate +NADH +H+ (This conversion happens from glucose to glucose 6 phosphate and then to fructose 6 Phosphate ,Fructose 1,6 bisphosphate and then to the above given step)

2. 1,3 bisphosphoglycerate +ADP ------>3,Phosphoglycerate +ATP

3. Phosphoenol pyruvate + ADP -------> Pyruvate + ATP( this is the last step in glycolysis)

4. Isocitrate +NAD ------------>alpha Ketoglutarate +NADH +H +CO2 (This happens in citric acid cycle,as pyruvate enters into krebs cycle as actyl Co A and enters as isocitrate)

5. Succinyl CoA + GDP +Pi -------->Succinate + GTP +CoASH

6. Fumerate +H2O ------------------->Malate

Malate +NAD+ -------------------------->Oxaloacetate + NADH+ H+
