Kreb's Cycle (also known as the citric acid cycle or TCA cycle) is a series of biochemical reactions that occur in the mitochondria of cells. It is a crucial part of cellular respiration, which is the process by which cells produce energy.
The Kreb's Cycle is important because it is the primary source of ATP (energy) production in cells. It also plays a role in the production of important molecules such as amino acids and fatty acids, which are essential for various cellular processes.
The Kreb's Cycle begins with the breakdown of glucose (sugar) into pyruvate. The pyruvate then enters the mitochondria and undergoes a series of reactions, which ultimately result in the production of ATP. Along the way, several intermediate molecules are produced, which are used to produce other important molecules.
During the isomerisation step of the Kreb's Cycle, the molecule citrate is converted into isocitrate. This reaction requires the addition of a water molecule to proceed, making H2O an essential component of this step. The water molecule is later removed in a subsequent step, completing the isomerisation process.
If there is not enough H2O in the isomerisation step, the reaction will not be able to proceed, and the cycle will be disrupted. This can lead to a decrease in ATP production and a buildup of certain intermediate molecules, which can have negative effects on the cell's metabolism and overall function.
