  glycolysis
Glycolysis (from Greek glyk meaning sweet and lysis meaning dissolving) is the inital stage of glucose metabolism.
Glycolysis converts 1 molecule of glucose into 2 molecules of pyruvate, along with "reducing equivalents" in the form of NADH.
Glycolysis is the only metabolic pathway common to nearly all living organisms, suggesting great antiquity; it may have originated with the first prokaryotes, 3.5 billion years ago or more.

Glycolysis occurs in two major stages, the first of which is the conversion of the various sugars to a common intermediate, glucose-6-phosphate.
Glycolysis itself is completely anaerobic; that is, oxygen is not required.

 Lactic acid - Wikipedia, the free encyclopedia
While lactic acid accumulation is one of the limiting factors in exercise, Delayed onset muscle soreness, which becomes apparent more than 24 hours after exercising, is not (as was once thought) caused by lactic acid buildup.
During one form of anerobic glycolysis or fermentation, L-lactate is produced from pyruvate via the enzyme lactate dehydrogenase.
Lactic acid fermentation can occur in red blood cells, because they lack mitochondria, and in skeletal muscle during intense exertion and when sufficient amounts of oxygen cannot be supplied fast enough.

In other words glycolysis must operate anaerobically when the rate of NADH production exceeds the rate at which it can be oxidised back to NAD+ by mitochondria.
Although anerobic glycolysis is not as efficient as aerobic glycolysis (because there is only scope for producing 2 ATP per glucose) it does provide a way for cells to meet increased demand for ATP when anerobic glycolysis is already opperating at its maximum possible rate.
You can see that anerobic glycolysis removes the metabolic load from the muscles and leaves it for the liver to deal with later.

 Glycolysis
b1) although lacate is shown, pyruvate is actually produced in both aerobic and anerobic glycolysis.
However, pyruvate is CONVERTED to lactate (by lactate dehydrogenase) in the absence of oxygen to regenerate NAD which is required for glycolysis.
Since NAD is required for one of the steps in glycolysis, without it glycolysis stops and no ATP is made: very bad.

 Question about lactic acid   (Site not responding. Last check: 2007-11-03)
It is the same acid that's in sour milk, cheese and yogurt, and is also produced in the anerobic fermentation of cabbage (eg sauerkraut).
Apparently the process is closely related to the anerobic glycolysis which occurs in the muscles.
And so at the end of glycolysis is a process called the electron transport system that assimilates O2 to generate CO2 + H2O (C comes from glucose) and replenish the supply of NADH and also generate ATP.

 Re: How many ATP are generated ?
Lactic Acid is the byproduct of glycolysis under anerobic conditions.
I believe that Lactic Acid is converted back into Pyruvate in the liver, and that Pyruvate is then released from the liver into the blood stream where it is picked up by needy tissues.
However, since Pyruvate is generated from Lactic Acid in your question, we can add the 1.5 ATP generated from the NADH made when Lactic Acid was convereted to Pyruvate in Lactic Acid's favor, so that 14 ATP equivalents are generated for each Lactic Acid that is oxidized.

Rosetting reduces blood flow, encourages cytoadherence to endothelium, enhances anerobic glycolysis and reduces the pH.
Unbridled cytoadherence-rosetting-sequestration results in poor tissue perfusion, organ dysfunction, anerobic glycolysis in tissues and lactic acidosis, malfunctioning of dendritic cells and T cells due to CD36 binding.
While low levels of cytokines may be beneficial, high levels are found to be harmful, contributing to placental dysfunction, suppression of erythropoeisis, inhibition of gluconeogenesis and increased cytoadherence.
