What is pyruvate converted into if oxygen is not available?

Question

I am doing a lab in Biology and the above question is one I cannot seem to find the answe for, can anyone help me

Answer 1

Hi Peter,

Pyruvate the end product of glycolysis is fermented in the absence of oxygen. So instead of complete oxidation of glucose the partially oxidized form pyruvate is converted to alcohol (ethanol) or to acid (eg. Lactic acid).

Fermentation, though low ATP yielding, is resorted to for regeneration of NAD.

Hope this helps
