The complete combustion of glucose in respiration is represented by:

• A
  $C_{6}H_{12}O_{6} + 6O_{2} \rightarrow 6CO_{2} + 6H_{2}O + \text{Energy}$
• B
  $C_{6}H_{12}O_{6} + 6CO_{2} \rightarrow 6O_{2} + 6H_{2}O + \text{Energy}$
• C
  $C_{6}H_{12}O_{6} + 6O_{2} + 6CO_{2} \rightarrow 6CO_{2} + 6H_{2}O + \text{Energy}$
• D
  $C_{6}H_{12}O_{6} + 6O_{2} \rightarrow 6CO_{2} + ATP \rightarrow 6CO_{2} + 6H_{2}O + 6O_{2} + \text{Energy}$
