The splitting of 6C glucose molecule
into two 3C pyruvate molecules.
1) Glucose must be made more reactive through
the addition of two phosphate molecules which are
provided from the hydrolysis of ATP to ADP. This
provides the energy to activate glucose.
2) Each glucose molecule is split into
two 3C triose phosphate molecules.
3) Hydrogen is removed from each of the TP molecules
and transferred to NAD (hydrogen-carrier) into NADH.
4) Enzyme-controlled reactions convert each TP into a
3C pyruvate molecule. During this process, two
molecules of ATP are regenerated from APD.
In anaerobic respiration, the pyruvate can be
fermented into either alcohol or lactate.
