1) Glycoloysis

1) Glycoloysis

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.
1. Alcohol fermentation:
2. Lactate fermentation:
Occurs in the cytoplasm of the cell.
