As the Glucose molecule 1 engine ", as there are 2 Pyruvate molecules, all 10 steps is divided into 2 phases: phase Energy and Energy generation is invesment phase.
A decomposition reaction Glucose 1 Pyruvate 2 molecule to a molecule with 10 stages divided into two steps, namely the Energy invesment phase and Energy generation phase.
Metabolic reaction Glucose 1 molecules, as Pyruvate 2 molecules are all 10 process is divided into 2 step digest is is Energy. Invesment phase Energy generation and phase.
