In the presence of sunlight and chlorophyll, the full equation for photosynthesis is:

•  $6CO_{ }+6H_2O\ \rightarrow\ C_6H_{12}O_6\ +6O_{ }$  

•  $C_6H_6O_6\ +6O_2\ \rightarrow\ 6CO_2+6H_2O\ \$  

•  $6CO_2+6H_2O\ \rightarrow\ C_6H_{12}O_6\ +6O_2$  

•  $C_6H_{12}O_6\ +6O_2\ \rightarrow\ 6CO_2+6H_2O\ \$
