Which equation best models cellular respiration?(1 point)
Responses
C6H12O6 + 6O2 + 6CO2 → 6H2O + Energy
C 6 H 12 O 6 + 6O 2 + 6CO 2 → 6H 2 O + Energy
C6H12O6 + 6O2 → 6H2O + 6CO2 + Energy
C 6 H 12 O 6 + 6O 2 → 6H 2 O + 6CO 2 + Energy
6H2O + 6CO2 → C6H12O6 + 6O2 + Energy
6H 2 O + 6CO 2 → C 6 H 12 O 6 + 6O 2 + Energy
6H2O + 6CO2 + Energy → C6H12O6 + 6O2
Responses
C6H12O6 + 6O2 + 6CO2 → 6H2O + Energy
C 6 H 12 O 6 + 6O 2 + 6CO 2 → 6H 2 O + Energy
C6H12O6 + 6O2 → 6H2O + 6CO2 + Energy
C 6 H 12 O 6 + 6O 2 → 6H 2 O + 6CO 2 + Energy
6H2O + 6CO2 → C6H12O6 + 6O2 + Energy
