write equations to show how lactic acid fermentation compares with alcoholic fermentation. which reactant(s) do they have in common?

Respuesta :

Alcoholic: Pyruvic acid + NADH → Alcohol + CO2 + NAD+

Lactic Acid: Pyruvic acid + NADH → Lactic acid + NAD+

All reactants are the same, but the products (except for NAD+) are different.


Hope this helps!

C6H12O6 --> 2CH3CH(OH)CO2H is the equation of lactic acid fermentation whereas  C6H12O6 ----> 2 C2H5OH + 2 CO is the equation of alcoholic fermentation.

We can see in the above two equation that in both lactic acid fermentation and alcoholic fermentation, one reactant is used which is glucose that turn into different types of products due to different fermentation processes.

In alcoholic fermentation, glucose molecule turn into ethanol and carbondioxide gas whereas in lactic acid fermentation, glucose molecule turn into lactic acid so we can conclude that glucose is the common reactant in both lactic acid fermentation and alcohol fermentation.
