Answer to Question #286077 in Cell Biology for Danna

Question

What do you think is the importance of the cyclic electron flow to the process of photosynthesis and the cell?

Answer 1

The light reactions in photosynthesis convert light energy into chemical energy in the forms of ATP and NADPH. The role of cyclic electron transport around PS I is proposed essential for balancing the ATP/NADPH production ratio and/or for protecting both photosystems from the damage via stromal over-reduction.
