Tricarboxylic acid cycle (TCA cycle)

The Tricarboxylic Acid (TCA) cycle, also known as the Krebs or Citric Acid cycle, is a fundamental process in our cells that generates energy. It takes nutrients from food, mainly sugars and fats, and breaks them down in a series of chemical reactions. These reactions produce energy-rich molecules like ATP, which powers our body's functions. Additionally, the cycle produces carbon dioxide as a waste, which we exhale. This cycle is central to how our cells turn food into usable energy, supporting everything from muscle movement to brain activity.
