The energy releasing process in which the substrate is oxidised without an external electron acceptor is called
Glycolysis
Fermentation
Photorespiration
Aerobic respiration
Solution
Fermentation consumes $\mathrm{NADH}_2$ and $\mathrm{e}^{-}$acceptor is released as $\mathrm{NAD}^{+}$not used. While glycolysis uses external $\mathrm{e}^{-}$acceptor as $\mathrm{NAD}^{+}$.
