Here's why:
* What is glycolysis? Glycolysis is the breakdown of glucose (a sugar) into pyruvate. It's the first step in cellular respiration, the process by which organisms obtain energy from food.
* Why doesn't it need oxygen? Glycolysis occurs in the cytoplasm of cells, and doesn't require oxygen to function. It's an anaerobic process, meaning it can happen without oxygen.
