Final answer:
From one glucose molecule, two lactate molecules are produced under anaerobic glycolysis with a net yield of two ATP molecules.
Step-by-step explanation:
Under anaerobic conditions, when a single glucose molecule undergoes glycolysis, a net total of two lactate molecules are produced. This is because glycolysis converts one glucose molecule into two pyruvate molecules, which are then each reduced to form lactate, regenerating NAD+ in the process. This reaction also produces a net yield of two ATP molecules as despite four ATPs being produced during glycolysis, two are consumed at the beginning of the glycolytic process.
