Tricarboxylic Acid Cycle (TCA) / Citric acid cycle

The Tricarboxylic Acid Cycle (TCA) / Citric acid cycle is central to cellular energy metabolism, oxidizing acetyl CoA to CO2, it also serves as a source of precursors for various biosynthetic pathways. The Tricarboxylic Acid Cycle (TCA) / Citric acid cycle cannot fully oxidize four or five carbon intermediates.

Tricarboxylic acid cycle (TCA) cycle metabolites regulate NLRP3 Inflammasome

Tricarboxylic Acid Cycle (TCA) / Citric acid cycle = Process by which acetyl coenzyme A is oxidized to form GTP, FADH 2 and NADH. NADH and FADH 2 feed electrons to the electron transport chain to produce ATP by oxidative phosphorylation. Several neurotransmitters (acetylcholine, glutamate and GABA) are produced by carbon leaving the TCA cycle
