Answer:
fermentation.
Explanation:
Alcohol, C02 and lactic acids are the end products of fermentation. This reaction pathway occur in the cytoplasm of cells in absence of oxygen.
In yeast cells it involved the removal of hydrogen atom from NADH to form NAD, for Glycolysis to continue, so that the 2 ATPs spent for glucose production in glycolysis, could be replaced.
The pyruvate from glycolysis is decarboxylated (removal of CO2 )to Ethanal. The C02 is liberated.The ethanal is reduced to Ethanol by the hydrogen removed from NAD. This is alcoholic fermentation.
Other organisms including man, undergo Latic acid fermentation,where the pyruvate from glycolysis is reduced to lactic acid from the hydrogen removed from NAD.
