Question

glucose can be broken down without the use of oxygen through the pathway.

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose into pyruvate. It occurs in the cytoplasm of cells and does not require oxygen. While further breakdown of pyruvate may require oxygen (in aerobic respiration) or proceed without it (in fermentation), the initial breakdown of glucose without oxygen is through glycolysis.

Answer:

Glycolysis
