Somebody me list the products of glycolysis. how many atp molecules are producedand consumed by glycolysis? what effect does the presence of oxygen have on the events that follow glycolysis?

In Glycolysis, each molecule of glucose yields 2 molecules of pyruvate, 2 molecules of NADH, and a net of 2 molecules of ATP. 
Energy in the form of ATP (adenosine tri-phosphate).Glycolysis takes 1 molecule of glucose and turns it into energy the body can use. Glycolysis is not dependent on Oxygen so Oxygen concentrations don't effect glycolysis.

No because the eaeht is on a 23.5 degree axis tilt and so when it is winter the northern hemisphere is pointing away from the sun and the soutubern hemisphere is pointing toward the sun
