In glycolysis net production of 2 ATP.Krebs cycle production is 1 ATP(1 molecule of GTP) and with ETS total production is 12Atp.


Glycolysis used 2 ATP and 4 ATP made.So net ATP produced is 2 ATP. Krabs Cycle with ETS 3 molecule NADH(#3*3=9# ATP) 1 molecule FADH2 (#2*1=2# ATP) and 1 molecule GTP(1 ATP).So total 12ATP produced in Krebs cycle.
