exergonic and endergonic processes.
« on: June 21, 2008, 01:09:05 PM »
Hello Biochemists.

I am just studying exergonic and endergonic processes and I am wondering if you can verify if my rational is correct.

        Glycolysis: the breakdown of glucose is an exergonic process.
     Lactic Acid Fermentation: endergonic process due to encorporation of ATP and NADH
   Cyclic electron Flow:exergonic
   Calvin Cycle: endergonic process

Am I correct on my assumptions of the above biochemical processes?

Thank you so much

Lactic acid fermentation does not use up ATP, but I would agree that it is endergonic because it requires energy from the oxidation of NADH to proceed.

I think I've seen the same post in the Organic chemistry thread..
well, I don't think that it's an endergonic reaction, because when lactate is reconverted into pyruvate in the liver, the NAD+ is reduced again into NADH. So I can say that lactic acid fermentation (pyruvate into lactate) is an equilibrium reaction.
