Question

Identifies the substance formed in fermentation....​

Answer 1

In alcoholic fermentation it begins with the breakdown of sugar by yeast to form pyruvate molecules which is also called as glycosis.

Answer 2

Fermentation reacts NADH with an endogenous, organic electron acceptor. Usually this is pyruvate formed from sugar through glycolysis. The reaction produces NAD+ and an organic product, typical examples being ethanol, lactic acid, and hydrogen gas (H2), and often also carbon dioxide.
