Question

how availability of oxygen predicts the fate of pyruvate ?​

Answer 1

Answer:

When oxygen is not present, pyruvate will undergo a process called fermentation. In the process of fermentation the NADH + H+ from glycolysis will be recycled back to NAD+ so that glycolysis can continue. In the process of glycolysis, NAD+ is reduced to form NADH + H+.

Answer 2

Answer:

The presence or absence of oxygen determines the fates of the pyruvate and the NADH produced in glycolysis. ... The conversion to lactate or ethanol under anaerobic conditions allows for the reoxidation of NADH to NAD+ in the absence of oxygen.
