Could someone please confirm whether this is correct
I'm hoping somebody could help me with the following question.
Is aerobic respiration more effective than anaerobic respiration in generating ATP because carbon dioxide and water are produced in the mitochondrion.
My own thoughts are that both statements are true but they are independent of one another, but that's me reading between the lines as well as looking at the Krebs cycle, as none of the books I've been searching in give a direct answer.
Your help would be appreciated, so thanks in advance to anyone who answers.

Aerobic resp - for ea mol Glucose i think it is 38 mols ATP
anaerobic resp - something like 6
so aerobic resp wins!
because Co2 and water are produced in the mitochondrion....which is true....
But is there causality....well I think not. I think aerobic resp is more efficient because biochemically, more energy can be released and it doesnt matter where.....
I know this is difficult - I hope the above allows you to make the right choice
Hi gen2
Thanks for responding to this, now I'm slightly confused. Do you think that aerobic respiration is more effective because the CO2 and water is produced in the mitochondrion and therefore the extra energy is released. Sorry to question your answer, but it has now got me thinking again when I thought I maybe had it sussed.
The this is that there are 4 main sections of respiration, glycolysis, the bridging reaction, krebs cycle and the electron transport chain (ETC).
During anaerobic respiration the bridging reaction cant occur (so krebs and ETC cant either), so only only glycolysis happens, which only produces 6 moles of ATP from 1 mol of glucose. CO2 is also produced during the bridging reaction so that is why it is not produced during anaerobic respiration.
