Answer:
Lactic acid fermentation
Explanation:
Lactic acid fermentation is the process that is utilized by the cell to produce energy in the form of ATP. it is the process by which glucose and other six-carbon sugars and also some disaccharides are converted into energy and the metabolite lactate, which is lactic acid in solution.
Due to the absence of oxygen, this process converts 3-carbon pyruvate to the 3-carbon lactic acid in the cytoplasm producing NAD+, allowing glycolysis to continue to produce ATP in low-oxygen conditions. although accumulation of lactic acid can lead to cramps.
