Can someone explain it like all the specific enzymes and reactions
With lactate fermentation is pyruvate reduced to lactate or lactic acid
You have the reaction glucose —>pyruvate. This requires all the glycolytic enzymes and produces NADH and ATP (the desired end product). However, the NADH is unable to enter the mitochondria for the electron transport chain (and be oxidised to NAD+) in anaerobic conditions, so it stays in the cytosol. You need to regenerate NAD+ somehow.
Meanwhile pyruvate will be converted to ethanal by pyruvate decarboxylase (removal of a carboxyl= releases CO2).
Ethanal will be reduced to ethanol by NADH (NADH unloads its proton to ethanal and is oxidised to NAD+, which is required for glycolysis).
Lactate and lactic acid are used interchangeably. Lactate is the deprotonated form of lactic acid (with a negative charge) ie its conjugate base. The enzyme that converts pyruvate to lactate is called lactate dehydrogenase.
