The light reactions of photosynthesis are said to be similar to a battery because they form a current. In which direction do the electrons of this circuit flow?
A) H2O → PSII → electron transport chain → PSI → electron transport chain → NADPH
B) H2O → PSII → chlorophyll b → PSI → chlorophyll a → NADPH
C) NADPH → PSII → electron transport chain → PSI → electron transport chain → NADP+
D) NADP+ → PSII → electron transport chain → PSI → electron transport chain → NADPH
E) PSI → electron transport chain → PSII → electron transport chain → NADPH
