STAGE ONE- PHOSPHORYLATION
First ATP is used to phosphorylate glucose to triose phosphate
NOTE THIS IS ALL FOR AEROBIC
A phosphate molecule from ATP is added to glucose (6C) - it is phosphorylated. This creates one ADP and one glucose phosphate (6C)
ATP then gives glucose phosphate another phosphate to make hexose biphosphate (6C)
Hexose biphosphate then splits into two molecules of triose phosphate (2X 3C)
STAGE TWO- OXIDATION
The two molecules of triose phosphate get oxidised to release ATP
Triose phosphate (2X 3C) gets oxidised which means it loses hydrogen which forms two molecules of pyruvate (2X 3C)
The hydrogen is given to NAD to form 2 molecules of reduced NAD
4 ATP overall are produced BUT two of these get used in stage one so there is a net gain of 2 ATP
2 ATP + 2 REDUCED NAD
2 PYRUVATE
