During glycolysis, glucose (C6) is broken down to two molecules of pyruvate (C3). (*Compounds that end in "___ate" can be called "___ic acid". Example lactate is lactic acid and malate is malic acid.)
Glycolysis occurs in the cytoplasm (cytosol) and does not require oxygen.
There are ten steps in glycolysis and each one is catalyzed by a specific enzyme. A brief summary of these reactions is presented here.
2 ATP molecules are used to phosphorylate and activate compounds that will eventually become converted to pyruvate (or pyruvic acid) (see diagram below).
Two hydrogen atoms are removed by NAD+ forming 2 NADH (see diagram).
Additional phosphorylation results in intermediate 3-carbon molecules with 2 phosphate groups.
Four ATP are produced by substrate-level phosphorylation. Recall that substrate-level phosphorylation is the production of ATP using energy from other high-energy compounds but without the use of the electron transport system in the mitochondria.
The net yield of ATP in glycolysis is 2 for each glucose molecule (2 are used but 4 are produced).
Some bacteria have alternative energy-producing reactions. Two of these are the pentose phosphate pathway and the Entner-Doudoroff pathway.
in short
4 ATP produced
-2 ATP consumed
________________
2 ATP net
2 NADH are also produced

4 ATP molecules. 1 molecule each is produced at levels 7 and 10. Since there are 2 isomers are produced at step 5, the second part is performed twice, giving a total of 4 molecules.

The NADH produce by glycolysis in the cytoplasm cannot cross the mitochondrial membrane. Instead, it gives up its electrons to a shuttle in the membrane, which then passes them to FAD+, yielding 2 ATP during electron transport.

as far as i can remember, you can prodce one ATP for each pyruvate produced from a single glucose....
