Question 9

What is the balanced chemical equation for aerobic respiration?

A

6CO2+6H2O→C6H12O6+6O26\text{CO}_2 + 6\text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_26CO2​+6H2​O→C6​H12​O6​+6O2​

B

C6H12O6+6O2→6CO2+6H2O\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}C6​H12​O6​+6O2​→6CO2​+6H2​O

C

C6H12O6+3O2→3CO2+3H2O\text{C}_6\text{H}_{12}\text{O}_6 + 3\text{O}_2 \rightarrow 3\text{CO}_2 + 3\text{H}_2\text{O}C6​H12​O6​+3O2​→3CO2​+3H2​O

D

6CO2+6O2→C6H12O6+6H2O6\text{CO}_2 + 6\text{O}_2 \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{H}_2\text{O}6CO2​+6O2​→C6​H12​O6​+6H2​O
