Question

Which among the following statements are correct with respect to anaerobic respiration?

• A. End products can be lactic acid and energy
• B. Takes place in the presence of oxygen
• C. Takes place in the absence of oxygen
• D. End products can be ${\mathrm{CO}}_2$, water and energy

Answer 1

Answer: (A), (C)

Takes place in the absence of oxygen

When glucose is broken down without using oxygen it is known as anaerobic respiration. Less energy is produced in anaerobic respiration. For e.g., yeasts breakdown glucose anaerobically into alcohol and carbon dioxide and releases energy. In muscle cells glucose is metabolised to lactic acid without using oxygen.
