The significance of the Krebs cycle

- Pyruvate is broken down into CO2 - Produces H2 that is carried by NAD to the ETC + provide energy for oxidative phosphorylation - Leads to the production of ATP that provides metabolic energy for the cell - Regenerates the 4 C molecule that combines with acetylco A, which would otherwise accumulate - Source of intermediate compounds used by cells in the manufacture of fatty acids, amino acids + chlorophyll
