What is the name of the process that breaks glucose down into the pyruvate that is used in cellular respiration?

The correct answer is Glycolysis.

At the time of glycolysis, glucose gets dissociated down into ten steps to two molecules of pyruvate that then moves within the mitochondria where it is oxidized by the process of the tricarboxylic acid cycle or Kreb's cycle into water and carbon dioxide. Glycolysis can be divided into two phases, and both of which takes place in the cytosol.
