What are the main events of glycolysis and how is ATP formed? What is the net yield in ATP from Glycolysis?

Answer 1

In glycolysis, glucose is broken down into 2 pyruvate molecules. 2 ATP are used, 4 are made for a net of 2 ATP. Two NADH are also made, which are transported into the mitochondrion (using 2 ATP) and 6 ATP are made for an additional net of 4 ATP. Here is an overview picture:
