Hello,
The explanation is that cell A was fermented (anaerobically), and cell B proceeded with cellular respiration (aerobic).
Lactic fermentation is a catabolic process, a fermentation, having as a starting point glycolysis, which produces an acid, lactic acid used to reoxidize NADH. In other words, lactic acid fermentation is a biological process by which sugars such as glucose, fructose, and sucrose are converted into cellular energy and metabolic byproduct, lactate. It is a lactic ferment that intervenes.
I hope this helps!!!! Happy Holidays!!!! (:
