The Krebs cycle, also known as the citric acid cycle, is stimulated primarily by the availability of substrates such as acetyl-CoA, which is derived from carbohydrates, fats, and proteins. Additionally, high levels of ADP and inorganic phosphate (Pi) promote the cycle's activity by indicating a need for ATP production. Conversely, increased concentrations of ATP and NADH can inhibit the cycle, signaling sufficient energy availability.
