Answer #1

Citric acid cycle or TCA or Krebs cycle is a metabolic pathway localized in the mitochondrial matrix.

The TCA cycle performs many functions.

It is the heart of the energetic metabolism of the cell, ie;almost all pathways of the energetic metabolism are connected to the TCA cycle. For example the ETC (electron transport chain), gluconeogenesis,transamination,deamination of amino acids or lipogenesis. It is quit obvious that there are both catabolic and anabolic pathways thus it is not easy to state which is dominant . This is the reason why it is described as amphibolic pathway
