Overview of the citric acid cycle

The citric acid cycle (CAC) also known as the TCA cycle (tricarboxcylic acid cycle) or the Krebs cycle is a series of enzyme-catalyzed chemical reactions that allow for aerobic respiration to occur within the mitochondria of the cell. When this cycle or its associated parts[1] are not functioning properly subsequent fatigue may take place.

Citric acid cycle in ME/CFS[edit | edit source]

A 2016 paper started to define how and why people with ME/CFS might experience poorly functioning cellular respiration[2]while a review of published papers [3] added empirical evidence of a relationship between mitochondrial dysfunction and fatigue.

According to Ron Davis, speaking at the 2016 IACFS/ME conference, "ME/CFS patients have a marked decrease in some of the Citric Acid Cycle metabolites while mitochondrial mutations generally cause an increase."[4]
