Question

Aerobic and anaerobic respirations differ from each other in all aspects except:

• A. Presence of absence of oxygen.
• B. Output of energy.
• C. End products.
• D. Breakdown of glucose in cytoplasm.

Answer 1

The correct option is D Breakdown of glucose in cytoplasm.

Aerobic respiration is the breakdown of glucose in the presence of oxygen and anaerobic respiration is the breakdown of energy in the absence of oxygen.

The energy released in aerobic respiration is higher as glucose is completely broken into CO₂ and H₂O whereas, in anaerobic respiration partial breakdown of glucose takes place and energy output is low.

Glycolysis, which converts glucose to pyruvic acid is the only common pathway that occurs in both aerobic and anaerobic respiration. It takes place in the cytoplasm.

So, the correct option is option D.
