Wait i've been told this differently.
1. glucose is goes through 2 phosphorylation reactions using 2 ATP this forms a more reactive fructose 1,6 bisphosphate and 2 ADP molecules
2. fructose 1,6 bisphosphate splits into 2 triose phosphate
3. the 2 triose phosphate then converted into 2 pyruvate molecules through oxidation. using 2 NAD,and producing 2 NADH. Additionally 4 ADP and 4 Pi are turned into 4 ATP during this stage.
4. resulting in a net gain of 2 ATP molecules.
i've been told its fructose 1,6 bisphosphate not hexose phosphate.
