The energy releasing metabolic process in which substrate is oxidised without an external electron acceptor is called
Photorespiration
Glycolysis
Fermentation
Aerobic respiration
Correct Answer: C
Solution:
In contrast to respiration, which involves the donation of electrons to an exogenous electron acceptor like oxygen via an electron transport chain, fermentation is the process of obtaining energy from the oxidation of organic compounds like carbohydrates while using an endogenous electron acceptor that is typically an organic compound and not external or exogenous.
