However, it's crucial to remember that the Krebs cycle is just one step in cellular respiration. The cycle also produces:

* 3 NADH molecules which, through oxidative phosphorylation, generate about 2.5 ATP molecules each.

* 1 FADH2 molecule which generates about 1.5 ATP molecules.

Therefore, while the Krebs cycle directly produces only 1 ATP, the total ATP generated from the products of one Krebs cycle is approximately:

* 3 NADH * 2.5 ATP/NADH = 7.5 ATP

* 1 FADH2 * 1.5 ATP/FADH2 = 1.5 ATP

Adding these to the direct ATP produced by the cycle:

* 1 ATP + 7.5 ATP + 1.5 ATP = 10 ATP

So, although the Krebs cycle directly produces only 1 ATP, the total ATP generated from the products of one cycle is about 10 ATP.
