Aerobic Respiration Equation Steps:

• Identify aerobic respiration as the process using oxygen to fully oxidize glucose into CO2 and H2O.
• Recall the balanced equation: C6H12O6 + 6O2 → 6CO2 + 6H2O.
• Check each option for balance, oxygen presence, and products.
• Eliminate unbalanced or oxygen-free equations.

Why A is correct:

• Matches the standard balanced formula for aerobic respiration, showing complete oxidation with oxygen yielding CO2 and H2O.

Why the others are wrong:

• B: Includes ethanol (C2H5OH), indicating fermentation, not full aerobic breakdown.
• C: Lacks oxygen, representing anaerobic alcoholic fermentation.
• D: Unbalanced coefficients and incomplete products, not a valid respiration equation.

Final answer: A
