Explanation / Answer

Ans. Anaerobic condition, lack of O2, does not permit occurrence of citric acid cycle and electron transport chain (both occur in mitochondria) because O2 would be required as the terminal electron acceptor for those pathways. Under such cases, only glycolysis, with net gain of 2 ATP, serves as the sole source of ATP in the cell.

# Glycolysis takes place in the cytosol of the cell.

# Therefore, anaerobic energy (ATP produced during anaerobic respiration) occurs in cytosol of the cell.

So, correct option is- C. Cytosol.
