Glycolysis
Usually whatever is being metabolised is first converted to Acetyl-CoA, for sugars this would be by sugar->pyruvate by glycolysis then pyruvate->Acetyl-CoA. This process yields a net gain in energy in the form of ATP. If no oxygen is present, then the proces goes no further. (see also: anaerobic metabolism )
Krebs cycle
When oxygen is present, Acetyl-CoA enters the krebs cycle, and gets converted to CO2 while at the same time converting NAD + H to NADH.
And Further
NADH can be used by several different processes to create further ATP.
Commonly Oxidative phosphorylation in the mitochondria, where oxygen is used to split the H off of NADH, and to produce further ATP in the process.
