Trace the movement of energy and matter through all photosynthetic processes.
Energy enters as light in the chloroplast, where it is utilized to create ATP and NADPH [in light-dependent reactions] which will aid in the formation of sugar in the calvin cycle. It then is cycled back into light-dependent reactions as ADP and NADP+ where it is formed back into ATP and NADPH with light energy.
Water is the first substance to enter the photosynthetic process, but it leaves as oxygen. Carbon dioxide enters next, and exits as sugar. These two processes occur simultaneously, the first in thylakoids, and the second in the stroma of the chloroplast in the calvin cycle.
