Question

Glucose Hexokinase ATP Glucose 6-phosphate Phosphoglucose isomerase Fructose 6-phosphate Phosphofructo- ATP kinase-1 ADP Dihydroxyacetone phosphate Fructose 1,6-bisphosphate Aldolase Triose 5 phosphate Glyceraldehyde isomerase 3-phosphate (2 molecules ) Glyceraldehyde 2 NAD+ +2P, 3-phosphate 2 NADH + 2H dehydrogenase I 1,3-Bisphosphoglycerate (2 molecules) 7 Phosphoglycerate 2ADP kinase 2 ATP 3-Phosphoglycerate (2 molecules) Phosphoglycero- mutase 2-Phosphoglycerate (2 molecules) Enolase. > 2H2O Phosphoenolpyruvate (2 molecules) Pyruvate 2 ADP kinase 2 ATP Pyruvate (2 molecules) How do you know one type of sugar yields more calories than the other? One way to figure this out is to calculate how much of energy one sugar contains in terms of ATP. Compare to the energy yield from one molecule of glucose, how much energy is produced from: • 1 molecule of fructose 6-phosphate • 1 molecule of glyceraldehyde 3-phosphate • 1 molecule of 1,3-bisphosphoglycerate • 1 molecule of 2 phosphoglycerate • 1 molecule of fructose • 1 molecule of sorbitol • 1 molecule of glycerol • If hexokinase is inhibited, how much energy would be produced from 1 molecule of glucose? • If phosphofructose kinase is inhibited, how much energy would be produced from 1 molecule of glucose? • If triose phosphate isomerase is inhibited, how much energy would be produced from 1 molecule of glucose? • If glyceraldehyde 3-phosphate dehydrogenase is inhibited, how much energy would be produced from 1 molecule of glucose? • If phosphoglycerate kinase if inhibited, how much energy would be produced from 1 molecule of glucose? • If pyruvate kinase is inhibited, how much energy would be produced from 1 molecule of glucose? 8

I am confused with this glucose structure, Can you answer the question asked on the right side of the page, please?

Answer 1

1 molecule of ducose = 2ATP consuned 4ATP produced 2Nянз 6 Ате 6+4-2= 8 ATP net Igento C3H803 gyceraldehyde 3P 6+4+299 Kop= d+d+6 -1 = 9 93p = 6+&+= 10 13 bpg = 2+2=4 apped free = qu=8 (C6H406) sorbit de = glu (C6H1406)

To count the number of ATP molecules from a given molecule, you have to count the number of ATP and NADH from that molecule only. For example to count the number of ATP molecules generated from fructose 6 phosphate, start counting the number of ATP and NADH produced from Fructose 6 phosphate onwards.

For counting the number of molecules produced from Fructose only, then Fructose and glucose are having same molecular formula for the number of ATP produced by fructose will be same as that of glucose.

Sorbitol is also having same chemical formula like that of glucose so the number of ATP molecules generated will be same.

Glycerol is having three carbon atom. First it will be phosphorylated to glyceraldehyde 3 phosphate by the consumption of one molecule of ATP. Then you simply have to count the number of ATP molecules generated by glycolysis of glyceraldehyde 3 phosphate.

According to rules, I can answer only first question. So I have answer till glycerol. Please give a high rating.
