Q31 / 199 · NEET 2008 (Mains) · Botany

The energy releasing process in which the substrate is oxidised without an external electron acceptor is called

A
Glycolysis
Correct answer
B
Fermentation
C
Photorespiration
D
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 $\mathrm{NAD}^{+}$.

Hence, the correct answer is option: 'B'.
