Produces:

Sugars (GLUCOSE

)ADP

NADP+

◦ Plants use the energy from ATP and NADPH to build high energy SUGARS (GLUCOSE) that can store energy for longer than a few minutes.

The carbon and oxygen needed to build the sugars come from CO2 in the atmosphere.

The Calvin cycle uses CO2, ATP and NADPH and creates Sugar, ADP and NADP+
