Pasteur demonstrated that yeasts and bacteria each produce specific metabolic products such as alcohols and organic acids using the metabolic pathway known as ________

Respuesta :

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.
