Glycolysis can occur without oxygen. Although glycolysis does not require oxygen, it does require NAD+. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.

This occurs via the process known as anaerobic respiration. The molecule lactic acid is used as the (temporary) electron acceptor instead of O2.

This is because the absorption of sodium is an energy-dependent process. Without an adequate oxygen supply, the cell will not have sufficient ATP available to absorb the sodium.
Glucose and NAD+
During fermentation, cells convert NADH to NAD+ by passing high-energy electrons back to pyruvic acid. This action converts NADH back into the electron carrier NAD+, allowing glycolysis to continue producing a steady supply of ATP.
To have a continous supply of energy, to help them reproduce and to live.

Glycolysis is the first step in releasing energy from glucose and therefore is supplying energy to the cell.

Anaerobic glycolysis
No they only supply us with oxygen,CO2
The tissues get oxygen from oxygenated blood supply for energy production.
sugar that is available in your blood stream gets used up first, then glycogen thru glycolysis breaks down, to supply the energy. After all sugar has been used, fat will be the next to be burnt by your body

The organism dies as no energy for even the simplest things, such as respiration and brain command, is available. Only in muscle cells can the organism switch to glycolysis for ATP production. The brain cells can not preform glycolysis.

When the body can't work fast enough to supply enough oxygen, glycolysis separates from the Kreb's cycle, and lactate is formed. Lactate is later broken down when there is enough oxygen. The breakdown of lactate is painful, which is why we get sore muscles after working out. When glycolysis and the Kreb's cycle separate, it is referred to as oxygen debt.
