The energy releasing process in which the substrate is oxidised without an external acceptor is called or Lactic acid converted into alcohol in process called

Options

A. glycolysis
B. fermentation
C. aerobic respiration
D. photorespiration

Answer

B

Explanation

Fermentation takes place in the lack of oxygen (when the electron transport chain is unusable ) and becomes the cell's primary means of ATP (energy) production. It turns NADH and pyruvate in the glycolysis into `NAD^(+)` and various small molecules depending on the type of fermentation . In the presence of `O_(2)` , NADH and pyruvate are used to generate ATP in respiration. It is called oxidative respriation.
