Explanation / Answer

Answer :

5. Fermaentation involves production of ATP in a process called Glycolysis, which produces much less ATP per glucosemolecule than oxidative phosphorylation and generally cayses the build-up of toxic byproducts because NAD+ must be regenerated by reduction of pyruvate.
