Respiration Quiz

What is the overall chemical equation during aerobic respiration?

• C6H12O6+6O2 → 6CO2+6H2O + 38 ATP + 420 kcal (Heat energy)

• C6H12O6 → lactic acid + 2 ATP + heat energy

• C6H12O6+6O2 → 6CO2+6H2O

• C6H12O6 → 6CO2+6H2O + 38 ATP + 420 kcal (Heat energy)

When does anaerobic respiration occur in animals?
