Re: Number of water molecules produced by cellular respiration

... conceal these water consumptions similar to the way that most textbooks never ever show that citrate formation consumes water as acetyl CoA and oxaloacetate combine. The other issue is that I have assumed that only one water is consumed in converting fumarate to malate or in forming citrate...what ...

solutions containing different concentrations of oxaloacetat

Did you see some real peaks with the oxaloacetate and malate or was it rather shifted baseline? (especially in the case of 1:10 dilution) As you can see, the absorbance of oxaloacetate and malate in range 4 - 0.8 mM is rather low if any. On ...

Please help!

1. Sorry, I intended to type Oxaloacetate, not "Ox.-Aloacetate". 2. Sorry, I mistyped that, obviously succinic acid is C4H6O4. 3. Yes, succinate does pass electrons to Coenzyme Q (Q to QH2) but I thought you were referring to ...

Please help!

1) it's difference between Ox.-Aloacetate and oxaloacetate 2) no, succinate is not C4O4, you're forgetting hydrogens :roll: 3) succinate doesn't enter the ETC. It just passes electrons to coenzyme Q, but otherwise is involved in TCA cycle, not in ETC
