What are the different ways in which glucose is oxidized to provide energy in various organisms?

There are various ways by which glucose is oxidized to provide energy, the first step is conversion of glucose to 2 molecules of pyruvate by glycolysis pathway which occurs in the cytoplasm of cells, then pyruvate is further broken down in various ways depending on the conditions:

• Anaerobic (absence of oxygen)
• Aerobic (presence of oxygen)
• Lack of oxygen
