Q. The energy releasing metabolic process in which the substrate is oxidised without an external electron acceptor is called :
(a) Glycolysis
(b) Fermentation
(c) Aerobic respiration
(d) Photorespiration
Solution :
Correct option : B Fermentation is an anaerobic pathway which takes place in certain bacteria and fungi which do not involve electron transport chain. In this process, substrate level phosphorylation takes place in glycolysis producing 2ATP molecules.
