During glycosis, glucose in broken down into?

The six carbon sugar, glucose, is cut in half and converted into two three carbon sugars called pyruvate. What happens next depends on the presence or absence of oxygen. If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water.

Pyruvate.

Explanation:

The glycolysis pathway, which occurs in the cytoplasm outside the mitochondria, is a broken-down process. It doesn't need oxygen. During glycolysis, glucose is broken down into pyruvate.

The first reactions of the glycolysis pathway produce triose phosphate, which produces ATP in the second sequence of reactions.
