The right answer are mentionned in the image.
The picture represents the cellular respiration.
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ENERGY
Cellular respiration is a chemical oxidation-reduction reaction that provides the energy needed for a cell to function.
Cell respiration requires:
a fuel: it is glucose, fatty acids or other organic molecules (amino acids, ketones);
an oxidizer, oxygen.
This reaction produces:
carbon dioxide;
some water ;
sometimes urea, if the fuel contains nitrogen (eg amino acids).
