TCA, Citric Acid Cycle- Hans Krebs cycle,
The citric acid cycle also known as the Krebs cycle or tricarboxylic acid (TCA) cycle. It is the second stage of cellular respiration. This cycle is catalizec by the several enzymes.
It is named in honor of the British scientist Hans Krebs who identified the series of steps involved in the citric acid cycle. The energy found in the carbohydrates, proteins and fats we eat is released mainly through the citric acid cycle. However the citric acid cycle doesn't use the oxygen directly. It works only when oxygen is present over there.
The first phase of cellular respiration is called glycolysis. Which are takes place in the cytosol of the cell's cytoplasm. The citric acid cycle occurs in the matrix of mitochondria's cell. In the biginbegi of the citric acid cycle, the pyruvic acid generated in glycolysis crosses the mitochondrial membrane and it is used for the formation of acetyl coenzyme A (acetyl CoA). Acetyl CoA is then used in the first step of the citric acid cycle. Each and every step in the cycle is catalizec by a specific enzyme.
Acetyl CoA:- it is a molecule that participates in many biochemical reactions in proteins, carbohydrates and lipids mechanism. It's main function is to deliver the acetyl group to the citric acid cycle (Krebs Cycle) to be oxidized for energy production.
Coenzyme A:- it is a coenzyme, and it is used for the Synthesis and oxidation of fatty acids and the oxidation of pyruvate in the citric Acid cycle.
