Why are Acetyl-CoA and succinyl-CoA, both high energy thioesters, chemical energies put to different uses?
The energy released by hydrolysis of acetyl-CoA is needed for the condensation reaction that links acetyl moiety to oxaloacetate, yielding citrate. The energy released by hydrolysis of succinyl-CoA drives the phosphorylation of GDP, yielding GTP
Some reactions of the citric acid cycle are endergonic. Explain how the overall cycle is exergonic.
The sum of the energies of the individual reactions is -44.3kJ for each mole of acetyl-CoA that enters the cycle
Which enzymes of the citric acid cycle are missing from the glyoxylate cycle?
isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and succinyl-CoA synthetase

Answer:
0.534
Explanation:
Mole fraction can be calculated using the formula:
Mole fraction = number of moles of solute ÷ number of moles of solvent and solute (solution).
In this question, solute is dimethyl ether while the solvent is methanol.
Mole (n) = mass (M) ÷ molar mass (MM)
Mole of solute (dimethyl ether) = 148.5 ÷ 46.07
= 3.22moles.
Mole of solvent (methanol) = 90 ÷ 32.04
= 2.81moles.
Total moles of solute and solvent = 3.22 + 2.81 = 6.03moles.
Mole fraction of dimethyl ether = number of moles of dimethyl ether ÷ number of moles of solution (dimethyl ether + methanol)
Mole fraction = 3.22/6.03
= 0.534
