Citric Acid Cycle

The Citric Acid Cycle (also known as the Krebs Cycle) is a series of reactions in the cells of living organisms that allow the body to convert food into energy. It is an essential part of the process of cellular respiration, which is necessary for life. The cycle begins with the ingestion of food, which is broken down and enters the cells as molecules called substrates. These substrates then undergo a series of enzymatic reactions, producing compounds known as intermediates. The intermediates are consumed by the energy-producing pathways, such as the electron transport chain, which generates ATP. The cycle is important in the production of energy and the removal of metabolic waste products, as well as its role in the production of important compounds, like amino acids and lipids.
