How many ATP are used and made in glycolysis, the Krebs cycle and the electron transport chain?

Answer 1

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.

Two ATP are produced in the Krebs cycle, four ATP are produced during glycolysis, and roughly thirty to forty-three ATP are produced during the electron transport chain.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
