Question

a - d are true regarding fermentation reactions, except: they are considered incomplete oxidations they supply nad+ for the oxidation of glucose they produce atp via an atpase (atp synthase) they operate in the absence of oxygen two of the above are correct

Explanation:

Fermentation occurs in the absence of oxygen and produces ATP through substrate - level phosphorylation, not via ATP synthase as in oxidative phosphorylation. It also regenerates NAD+ for glycolysis to continue. Fermentation is an incomplete oxidation of glucose.

Answer:

C. They produce ATP via an ATPase (ATP synthase)
