How much ATP does Oxidative Phosph. and the Electron Transport chain yield?

[Toothguy80]

Do Oxid. Phosph. and the Elelctron Trans. chain yield the same amount of ATP? Is it 32, 34?

I know that Glycolysis yields 2 and the maximum amount is 36 so can someone break it down for me as to exactly which yields how much ATP?

Another question:
The boiling-point elevation constant for water is approximately 0.5C/m. What is the boiling point of the solution when 0.5 moles of NaCl is dissolved in 2000 g of H2O?

for this, you have to get the molality of NACl and then multiply it by 2, but I forget to do that and just calculate molality. Do I always do that when there are ions involved. Can someone please explain?

Energetic considerations

• 3 NADH+3H+ formed/turn of the cycle
  • Approximately 3 ATP formed/NADH+H+ by electron transport and oxidative phosphorylation
• 1 FADH2 formed/turn of the cycle
  • 2 ATP formed per FADH2 by electron transport and oxidative phosphorylation
• 1 GTP formed/turn (equivalent to 1 ATP) (succinate thiokinase step)
• Total equivalent of 12 ATP formed/turn
  • 2 turns required for 2 acetyl-CoA's results in an equivalent of 24 ATP/2 acetyl-CoA's
• Energy Yield from glucose through Glycolysis and TCA Cycle
  • 2 mol ATP/glucose
    • Net from glucose to pyruvate
  • 2 mol GTP/glucose
    • 1 from each acetyl-CoA via TCA at succinly CoA synthetase
  • 10 NADH times 3 mole ATP/NADH = 30 ATP
    • 2 derived from glucose to 2 pyruvate via glycolysis (G3PDH)
    • 2 derived from 2 pyruvate to 2 acetyl-CoA (PDH)
    • 6 from 2 acetyl-CoA in TCA (MDH, KGDH, IDH)
  • 2 FADH times 2 mole ATP/FADH = 4 ATP
    • 1 for each Acetyl-CoA via TCA (SDH)
  Total = 38 ATP/mol glucose

This is a tally of all the ATP produced. This is a great summary. It shouldhelp you. Good luck.

For the second question, the answer is yes, because remember if water dissolves something it breaks its hydrogen bonds and binds salt ions. So, you need to figure out how much energy it would take to break the salt bridges so that solution with salt and water will start boiling. That is why you need to make this calculations when soluable solute in comes into the water. This will affect the boiling point.
Hope this helps,
Good luck.

Hey dotoday,
Thanks for posting this - I was just studying this topic an hour ago using the Kaplan book but this looks so much easier, comprehendable, as well as memorizable!🙂
