Question

the reduction of pyruvate to lactic acid during fermentation allows glycolysis to continue in the absence of o2 because this reaction is coupled to the formation of atp. is a kinase reaction. is coupled to the oxidation of nadh to nad+. is coupled to the reduction of nad+ to nadh. produces h2o.

Explanation:

In lactic - acid fermentation, the reduction of pyruvate to lactic acid is coupled with the oxidation of NADH to NAD+. This regeneration of NAD+ allows glycolysis to continue in the absence of oxygen as glycolysis requires NAD+ as an electron acceptor.

Answer:

is coupled to the oxidation of NADH to NAD+.
