Citric acid cycle (Krebs cycle)

The citric acid cycle, also known as the Krebs cycle, is a series ofchemical reactions that happen in our cells to generate energy. It takes in nutrients from food, especially glucose, and breaks them down step by step. This process releases energy stored in these nutrients, producing molecules like ATP that power our body's activities. Additionally, it releases other byproducts used in various functions. The cycle occurs in the mitochondria, the cell’s energy factories, and is essential for maintaining the energy balance necessary for life.
