Clinical Cuts: Glycolysis

Let’s say that you're munching on a big slice of pizza with onions, mushrooms, bell peppers, and jalapeños while watching today's #ClinicalCuts. Pulling energy out of the glucose in that pizza, or really any food, requires glycolysis.

Glycolysis is a series of enzymatic reactions in which glucose, a 6 carbon sugar molecule, is broken down into two 3 carbon pyruvate molecules. As glucose gets processed, energy is produced in the form of adenosine triphosphate, or ATP.

Glycolysis happens in the cytoplasm of cells, and no special organelles or even oxygen are needed to turn glucose into ATP. Therefore, all cells can use glucose to make energy, and it’s possible to do glycolysis even when oxygen levels are low.

Glycolysis can be divided into two phases: an energy-consuming phase, and an energy-producing phase.
