How the krebs cycle works
Nettet6. nov. 2024 · The krebs cycle is a series of chemical reactions that occur in the mitochondria of cells. These reactions convert the energy in food into a form that the cell can use to power its many functions. The krebs cycle begins with the breakdown of a sugar molecule called glucose. This process is called glycolysis.
