TCA cycle (tricarboxylic acid cycle)

The TCA cycle, also known as the Krebs cycle, is a series of biochemical reactions in cells that generates energy from nutrients like sugars and fats. It occurs in the mitochondria, the cell’s powerhouses. During the cycle, chemical compounds are broken down, releasing energy stored in bonds, which is captured in molecules called NADH and FADH2. These molecules then help produce ATP, the main energy currency cells use for various functions. Essentially, the TCA cycle is a central process that converts food into usable energy to keepcells active and functioning properly.
