Photos y nthes is animation. Pay c los e attention to the
role of light, the formation of NADPH and ATP, and
the us e of NADPH and ATP in s ugar produc tion. Part A Inputs and outputs of the light reactions
From the following c hoic es , identify thos e that are the inputs and outputs of the light reac tions . (Rec all that inputs to c hemic al reac tions are modified
ov er the c ours e of the reac tion as they are c onv erted into produc ts . In other words , if s omething is required for a reac tion to oc c ur, and it does not
remain in its original form when the reac tion is c omplete, 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”
bi n. Hin t 1. Energy conversion from one form to another in the light reactions
The light reac tions c onv ert one form of energy into the c hemic al energy of ATP molec ules . Think about the s ourc e of this energy and about
what is needed to mak e ATP molec ules . Hin t 2. Which energy sources produced in the light reactions will be used by the Calvin cycle?
Whic h of the following trans fer energy from the light reac tions to the Calv in c y c le?
Select all that apply.

The term “light reac tions ” implies that light play s s ome role in this s tage of photos y nthes is . Whic h of the following s tatements c orrec tly
des c ribes a role of light in the light reac tions ?
Which of the following statem ents correctly describes light's role?
Light s upplies the energy to remov e elec trons from water and to trans port thos e elec trons to NADP+.
Light prov ides the atoms that are needed to c onv ert ADP to ATP.
Light s upplies the elec trons that are needed to reduc e NADP+ to NADPH.
