The Krebs cycle, also known as the citric acid cycle, completes the oxidation of foodstuffs by transferring electrons to NAD+ and FAD, which act as hydrogen carriers. This process generates ATP and carbon dioxide as byproducts. The cycle starts with acetyl-CoA and ends with the regeneration of oxaloacetate, which can then be used to start the cycle again.
