Question:medium

The energetic efficiency (in terms of number of ATP equivalents per absorbed photon) of non-cyclic electron transport process in photosynthesis, after taking into account the ATPs yielded by NADPH produced in it, is:

Show Hint

While non-cyclic electron transport produces a fixed ratio of ATP to NADPH, plants can adjust this ratio using cyclic photophosphorylation, which generates ATP without producing additional NADPH to meet the exact energetic demands of the Calvin cycle.
