Biology Question on Fermentation
The energy-releasing metabolic process in which substrate is oxidised without an external electron acceptor is called
A
Photorespiration
B
Glycolysis
C
Fermentation
D
Aerobic respiration
Answer
Fermentation
Explanation
Solution
Fermentation is the process of deriving energy from the oxidation of organic compounds such as carbohydrates and using an endogenous electron acceptor not external or exogenous, which is usually an organic compound, as opposed to respiration where electrons are donated to an exogenous electron acceptor, such as oxygen via an electron transport chain.
