What is the cycle of citric acid?

Citric acid cycle is a number of chemical reactions that occur during cellular breathing, the process by which cells in organisms produce energy. It is also referred to as the Krebs cycle or a cycle of tricarboxylic acid. In the cycle, a number of chemical reactions are catalyzed or accelerated by various enzymes. Students usually study the cycle of citric acid in advanced classes of secondary school biology or on the introductory classes of the University Biology. It then approaches in more detail in biochemistry classes, because it is by its very nature a chemical process.

There are many different complex chemical reactions in the cycle, most of which include molecules composed of carbon, oxygen and hydrogen. The cycle is about ten steps and each step is catalyzed by a different enzyme. Immediately before the cycle of citric acid acid, a process called glycolysis produces energy, as the cell breathing process takes place. Citric acid cycle breaks the pyr moleculesUVat on the molecules of NADH (nicotinamide adenin dinucleotide) and ATP (adenosine triphosphate), which contain a significant amount of energy that the body can approach quickly. Most of the energy molecules produced during cellular breathing are through a number of metabolic processes derived from glucose molecules (sugar).

cell breathing is usually an aerobic process, which means it uses oxygen. If oxygen is present, the pyruvate produced by glycolosis will be normal for a citric acid cycle, which will be divided into NADH and ATP (adenosine triphosphate). However, if no oxygen is present, the pyruvate begins a process called fermentation . Fermentation does not use oxygen, which means it is an anaerobic process. Fermentation is much less effprocess energy production than a cycle of citric acid; It does not create enough energy to maintain the organism for a longer period of time.

in the most complex, mFootbun organisms are a cycle of citric acid in mitochondria, an energy organelle that exists inside the cells. Mitochondrion is the main ATP manufacturers that are able to use the cells very efficiently for energy. Some processes in cellular breathing occur outside mitochondria and others occur because the molecules are transported through the membrane of mitochondria. Citric acid cycle occurs in the matrix of mitochondria, which contains many different enzymes that catalyze many chemical reactions involved in the cycle and in the rest of cell breathing.
