From the following choices, identify those that are the inputs and outputs of the light reactions. (recall that inputs to chemical reactions are modified over the course of the reaction as they are converted into products. in other words, if something is required for a reaction to occur, and it does not remain in its original form when the reaction is complete, it is an input.) drag each item to the appropriate bin. if the item is not an input to or an output from the light reactions, drag it to the "not input or output" bin.
