Glycolysis is the conversion of _________ to _________ in the process of cellular respiration.

Glycolysis is the conversion of glucose to pyruvate, and it is the first step in the process of cellular respiration. Cellular respiration is the group of processes that fully oxidizes glucose to CO2 to make ATP; it includes glycolysis, the Krebs cycle, and the electron transport chain. Glucose is made from CO2 during the Calvin cycle of photosynthesis, not during glycolysis.
