Well for cellular respiration the inputs, or reactants, are glucose and oxygen. The outputs, or products, of cellular respiration are water, carbon dioxide and ATP molecules - ( adenosine triphosphate ). Photosynthesis is different, as expected, from cellular respiration. In photosynthesis the inputs are : 6H2O( water ), 6CO2( carbon dioxide ), ( light energy ).

and the outputs or the products of photosynthesis is C6H12O6 (glucose), 6O2 ( oxygen ).
