$(A)$ In fermentation,the reducing agent is $NADH + H^+$.
$(B)$ There are three major ways in which different cells handle pyruvic acid produced by glycolysis.
$(C)$ The complete oxidation of pyruvate occurs by the stepwise removal of all the hydrogen atoms,leaving two molecules of $CO_2$.
$(D)$ The $NADH$ synthesised in glycolysis is transferred into the mitochondria and undergoes oxidative phosphorylation.
$(E)$ Complex-$IV$ of $ETS$ refers to cytochrome $c$ oxidase complex.
