Question

'Anaerobic respiration involves oxidation of nutrients without utilising molecular oxygen.' Explain.

Answer 1

Dear student,

Anaerobic respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors.
It is used when there is not enough of oxygen to carry out aerobic respiration The end products are mostly lactic acid or alcohol and produces less amount of energy (2 ATP).
It occurs in many anaerobic bacteria and yeasts and in human muscle cells.
In muscles, lactic acid is produced while in bacteria or yeast produces alcohol (ethanol).

C₆H₁₂O₆ --> Lactic acid / C₂H₅OH + ATP
​(Glucose)
