Question: what is the difference between cyclic and non cyclic photophosphorylation?
Answer: Water will first be broken down into 4H+ ions and 4e- (electrons) and oxygen. ... So in non-cyclic photophosphorylation, you make oxygen, from splitting the water molecule, you make ATP using the H+ ions and you make NADPH. In cyclic photophosphorylation, you only use photosystem I.
