Oxidation of Pyruvate and the Citric Acid Cycle .

The citric acid cycle is also known as the Krebs cycle or the TCA (tricarboxylic acid) cycle. Acetyl CoA transfers its acetyl group to oxaloacetate to form citrate and begin the citric acid cycle. The release of carbon dioxide is coupled with the reduction of NAD + to NADH in the citric acid cycle.

Citric Acid - an overview | ScienceDirect Topics

In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of almost all living things. It also serves as an environmentally benign cleaning agent and acts as an antioxidant. Citric acid is produced by the fermentation of glucose. Approximately, 35 000 tons are consumed annually in Japan.

Anaplerotic reactions - Wikipedia

Malate, in the mitochondrial matrix, can be used to make pyruvate (catalyzed by malic enzyme) or oxaloacetic acid, both of which can enter the citric acid cycle. Glutamine can also be used to produce oxaloacetate during anaplerotic reactions in various cell types through "glutaminolysis", which is also seen in many c-Myc transformed cells.
