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!

Please answer the following question including how you arrivedto the answer. I asked this question earlier, and they did notexplain how they arrived tot the answer, and didn't answer all myquestions.

Consider the following reaction at 25 degrees celsius, Pyruvate+ Ethanol ----> Acetalaldehyde + Lactate

a). Using the data from table 10.4, calculate the standard freeenergy change for the reaction in kJ/mol.

Table 10.4: Standard Gibbs Free energies of hydrolysis forcommon metabolites:

Metabolite: Delta G hydrolysis (kJ mol ^-1)

Phosphoenolpyruvate -62

1, 3-Bisphosphoglycerate -49

ATP to AMP + PPi -45

Phosphocreatine -43

Phosphoarginine -32

Acetyl CoA -32

Acyl CoA -31

ATP to ADP + Pi -32

Pyrophosphate -29

Glucose 1-phosphate -21

Glucose 6-phosphate -14

Glycerol 3-phosphate -9

b). Is the reaction spontaneous as written?

c). If the concentration of concentrations of ethanol, pyruvate,and lactate are each 1.00 mM, what does the concentration ofacetaldehyde need to be to make the reaction spontaneous?
