What is the significance of the Krebs cycle?

The Krebs cycle is a metabolic pathway that allows for the final oxidative pathway for the products of the oxidation of carbohydrates, lipids, and amino acids.
The cycle is responsible for the complete oxidation of these products to CO2.
The cycle is a dual, amphibolic pathway that is both catabolic and anabolic.
The cycle is not related to the synthesis of glucose or glycogen.
