Final answer:
Pyruvate is the molecule created from glucose during glycolysis and can be further oxidized under aerobic conditions through the citric acid cycle.
Step-by-step explanation:
When glucose is broken down via glycolysis, the molecule that is created and can be oxidized under aerobic conditions is pyruvate. Once glucose has undergone glycolysis, two molecules of pyruvate are produced. These pyruvate molecules can then enter the mitochondrial matrix where they are fully oxidized during the citric acid cycle. This process involves their conversion to acetyl CoA, which then enters the Krebs cycle, contributing to the production of additional ATP as well as NADH and FADH2, which are used in the electron transport chain to generate a substantial amount of energy for the cell.
