Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.

What is the byproduct of lactic acid fermentation?

Lactic acid fermentation occurs in certain bacteria, yeast and muscle cells and converts glucose to energy. Its by-product is lactate.

What are the steps of lactic acid fermentation?

Lactic acid fermentation has two steps: glycolysis and NADH regeneration. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH.
