In the light dependent reactions of photosynthesis, the plant cell will conduct both linear and cyclic electron transport. This is needed because
A) electrons are accepted by ferrodoxin during electron transport and without this, ATP synthesis would not occur.
B) linear electron transport processes do not absorb enough light to allow for the synthesis of ATP.
C) more NADPH is needed compared to ATP in the subsequent light independent reactions Calvin cycle).
D) more ATP is needed compared to NADPH in the subsequent light independent reactions Calvin cycle).

Linear electron transport produces both ATP and NADPH, but the Calvin cycle consumes more ATP than NADPH. Cyclic electron transport allows for additional ATP production without producing more NADPH, balancing the ratio of these molecules for the Calvin cycle.
